INTRODUCTION ------------------------------------------------------------------ INTRODUCTION Welcome, and thanks for purchasing 4DOS, 4OS2, or 4NT! We started developing these products when we realized that our computers could be a lot more powerful and a lot more helpful than they were. Whether you are a computer novice or an experienced power user, we think that our products will help you get the most out of your IBM PC or compatible computer. We offer three different products which work with different operating systems: * You can use 4DOS with all versions of MS-DOS and PC-DOS from 3.1 through 7.1 and above ("MS-DOS 7" is the DOS portion of Microsoft Windows 95). You can also use it with all versions of DR DOS / Novell DOS / OpenDOS from 3.4 through 7.0 and above, and in DOS sessions started under Windows 3.0 or 3.1, Windows 95, OS/2 2.x, and OS/2 Warp 3 and 4. * You can use 4OS2 with OS/2 2.1 and above, and OS/2 Warp 3 and 4. * You can use 4NT with Windows NT 3.5, 3.51, 4.0, and above. Once you have 4DOS, 4OS2, or 4NT installed, you can learn to use it at your own pace. Each program has more than 90 commands and hundreds of enhanced features, but you don't have to learn them all, or learn them all at once. Relax, enjoy the program's power, and browse through the manual occasionally. Press the F1 key whenever you need help. 4DOS, 4OS2, or 4NT will soon become an essential part of your computer, and you'll wonder how you ever got along without it. We are constantly working to improve our products. If you have suggestions for features or commands that you think we should include in the next version, or any other way we could improve our product, please let us know. Many of the improvements in this version were suggested by our users, and while we can't promise to include every suggested feature, we really do appreciate and consider your comments. 4DOS, 4OS2, and 4NT are related programs that work in text or command-line mode. If you use Windows 3.x, Windows 95, Windows NT, or OS/2, we also offer Take Command, a graphical program that includes the power of 4DOS, 4OS2, and 4NT plus several additional features, and which runs in a desktop window. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 1 INTRODUCTION ------------------------------------------------------------------ * Take Command/16 runs under Windows 3.x, Windows for Workgroups, and Windows sessions in OS/2. * Take Command/32 runs under Windows 95 and Windows NT. * Take Command for OS/2 runs on the OS/2 Presentation Manager desktop. You can use these products to maintain a common working environment and run the same commands, batch files, and aliases under DOS, OS/2, Windows, Windows 95, and Windows NT. Additional products for use on the same system are available at a discounted price for 4DOS, 4OS2, and 4NT users. Our JP CD Suite includes all six products. Licenses for multiple systems are also available. Contact your software reseller or JP Software for more information. How to Use This Manual This manual is only one part of the documentation that you will need for 4DOS, 4OS2, or 4NT. It introduces the product and will help you install it correctly on your computer. It also gives you specific information about using the program in your particular environment (for example, using 4DOS under DOS, Windows, or OS/2). The second part of our documentation is the Reference Manual and the online help. They contain complete information about the commands and features of 4DOS, 4OS2, and 4NT. You should start with this introductory manual whether you are new to our programs or you are upgrading from a previous version. Once you have successfully installed 4DOS, 4OS2, or 4NT you can move on to the Reference Manual or the help for detailed information on commands, features, and configuration. The first three chapters of this manual introduce the products and help you install the program and its built-in help system. Chapters 4 _ 7 contain additional details about each product and operating environment. We encourage you to review the material in the later chapters to see what applies to you (particularly if you are using 4DOS under Windows 95 or OS/2, or with Novell Netware). However, in many cases you will not need the information in Chapters 4 _ 7 unless you are working at a more technical level, or run into some unexpected difficulty. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 2 INTRODUCTION ------------------------------------------------------------------ Most of the first part of this manual describes commands and features which are available in all three products. When we need to discuss the features or behavior of a single product, we mention it specifically in the text. When an entire paragraph or section applies to a specific product, we use marginal text to identify that product: 4DOS marks sections that apply only to 4DOS. 4OS2 marks sections that apply only to 4OS2. 4NT marks sections that apply only to 4NT. Each of our products also includes complete online help for all commands. The 4DOS and 4OS2 help systems can be configured to link to help on standard DOS and OS/2 commands as well, if the corresponding help files and programs are available on your system. Our online help provides much of the same information that is available in this manual and the Reference Manual, but in an electronic form which you can access quickly. The online help also includes details about changes in the latest version of our products, compatibility with other products, and additional technical information. See page 25 for more information about the online help. Finally, be sure to check README.TXT for last-minute notes on the current release, or if you are installing a downloaded update to 4DOS, 4OS2, or 4NT.

Technical Support Before You Contact Us Before contacting us for support, please check this manual, the Reference Manual, the online help, and other documentation for answers to your question. If you can't find what you need, try the Index. If you're having trouble getting 4DOS, 4OS2, or 4NT to run properly, see the Troubleshooting, Service, and Support topic in the online help for any relevant information (in 4DOS, check the Compatibility section as well), and look through the ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 4 INTRODUCTION ------------------------------------------------------------------ README.TXT file for any last-minute information for your product. If you do need to contact us for support, it helps if you can give us some basic information. The first four items listed below are essential for us to be able to understand and assist you with your problem: * What environment are you working in? This includes the operating system version are you using, the version of the JP Software product involved, and related information such as network connections and the name and version number of any other software which appears to be involved in the problem. Use the VER /R command to determine the command interpreter and operating system version. * What exactly did you do? A concise description of what steps you must take to make the problem appear is much more useful than a long analysis of what might be happening. * What did you expect to happen? Tell us the result you expected from the command or operation in question, so that we understand what you are trying to do. * What actually happened? At what point did the failure occur? If you saw an error message or other important or unusual information on the screen, what exactly did it say? * Briefly, what techniques did you use to try to resolve the problem? What results did you get? * If the problem seems related to startup and configuration issues, what are the contents of any startup files you use (such as CONFIG.SYS, AUTOEXEC.BAT, 4START, 4EXIT, and the .INI file), any batch files they call, and any alias or environment variable files they load? * Can you repeat the problem or does it occur randomly? If it's random, does it seem related to the programs you're using when the problem occurs? If you have a problem with a batch file or complex alias, please contact us electronically if possible. Include an exact copy of the batch file or alias in question, preferably as part of the text of your message (not as an attachment). ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 5 INTRODUCTION ------------------------------------------------------------------ If you do not have electronic access, contact us by fax if possible. Problems of this type are usually very difficult to diagnose over the telephone because we cannot see the material you are working with. If your batch file is longer than about 20 lines, please try to reproduce the problem in a smaller test file; otherwise it will probably be impossible for us to understand and recreate the difficulty you found. If you need more in-depth assistance with the development of complex batch files or other procedures, please contact us for information on consulting services. Electronic Support Usually the best way to contact us for support is via CompuServe or the Internet. The most efficient method is to use our CompuServe support conference; if you do not have CompuServe access, contact us via Internet email. (Our CompuServe and Internet addresses are listed on page 3.) Whenever possible, we also read messages posted on the Usenet comp.os.msdos.4dos newsgroup, and in the 4DOS conference on the FidoNet BBS network (these discussion areas are named for 4DOS, but carry messages related to all JP Software products). These areas offer valuable information and discussions with other users, but are not managed by JP Software, and are not official support channels. To be certain of a direct answers from our support staff use our CompuServe forum, web site, or Internet email, or contact us by telephone, fax, or mail. Additional support resources are available from our web site at htp://www.jpsoft.com/, including error message listings, documentation files, product histories, technical tips and discussions, other technical information, and links to other companies' sites. We update this information regularly, and we encourage you to check the Technical Support area of the web site to see if the information there will address any questions you have. Telephone Support Telephone technical support within the US and Canada is handled on a callback basis. To contact our support staff, call our US / Canada Support Line at any time and leave a short voice mail message describing your technical problem. The telephone number is 617-646-0798, and will change to 781- 646-0798 effective September 1, 1997. This line can not be ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 6 INTRODUCTION ------------------------------------------------------------------ used for sales and customer service issues such as pricing, ordering, upgrades, or shipping problems. We check messages regularly throughout the day, and will return your call as quickly as possible. We generally return all technical support calls within 24 hours (weekends and holidays excluded), and most are returned much more quickly, usually on the same business day. If your problem is urgent and requires a faster response, please let us know and we will try to accommodate you. If you contact us by telephone and don't receive a reply within 24 hours, please try again. We may have tried to return your call and been unable to reach you. If you are calling from outside the US and Canada, are not sure if your question requires technical support, need other assistance in addition to your technical questions, or find yourself playing "telephone tag" with our support staff, please call our main number, 617-646-3975 (781-646-3975 effective September 1, 1997). Our office staff will assist you with all of your concerns, and have a technical support representative call you back if necessary. Registration and Upgrade Information If you purchased 4DOS, 4OS2, or 4NT from a software dealer, your copy came with a registration card. Please fill out this card and return it promptly to JP Software. It ensures that we have a record of your registration so that we can give you ongoing technical support and notices of upgrades. If you purchased 4DOS, 4OS2, or 4NT directly from JP Software, or ordered an electronic copy via our web site, you are already registered and no registration card is necessary. Once you are a registered user, with each notice of a major upgrade you will receive The Prompt Solution, JP Software's customer newsletter. The Prompt Solution also includes tips for using 4DOS, 4OS2, and 4NT, and information about other products from JP Software. Registration also entitles you to full technical support via electronic mail, fax, mail, or telephone. 4DOS, 4OS2, and 4NT are upgraded regularly through maintenance releases, designed to fix minor problems or improve compatibility, and major upgrades which contain enhancements and additional features. Maintenance releases are identified by a change in the hundredths digit of the version number, for example from 6.0 to 6.01 or 6.02, or in a letter suffix (e.g. 6.01B). Major upgrades are identified by ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 7 INTRODUCTION ------------------------------------------------------------------ a change in the tenths digit or "ones" digit, for example from 6.0 to 6.1 or 7.0. Major upgrades can be purchased from JP Software or your dealer. You can download maintenance releases from our web site (http://www.jpsoft.com/), or from the CompuServe or BBS locations listed under Contacting JP Software on page 3. You can also order them on disk at a nominal cost. As a registered user, you will automatically be notified when a major upgrade is released. We don't send out notices when maintenance releases become available, because you don't usually need them unless you're having a problem. If you call with a problem that's been addressed in a maintenance release, we'll mail you a copy on disk or assist you in downloading it. If you want to know when a product update is available, visit our web site at http://www.jpsoft.com/. Notices are posted there whenever one or more of our products is updated, and email or other automated methods for upgrade notification may become available on the web site in the future. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 8 Chapter 1 / Introducing 4DOS, 4OS2, and 4NT ------------------------------------------------------------------ Chapter 1 / Introducing 4DOS, 4OS2, and 4NT 4DOS, 4OS2, and 4NT are command interpreters or "Shells." That means that they display a C:\> or [C:\] prompt, wait for you to type something, and then react to your commands. Our programs replace the default command interpreters that are supplied with your operating system. 4DOS replaces COMMAND.COM for DOS, Windows 95, and for DOS sessions under OS/2. 4OS2 and 4NT replace CMD.EXE. We've designed our products so that you don't have to change your computing habits or unlearn anything to use them. If you know how to display a directory, copy a file, or start an application program, you already know how to use our command interpreters _ and if you're not used to using the command line, you'll appreciate our programs' comprehensive online help and the way they make the command prompt straightforward and easy to use. 4DOS, 4OS2, and 4NT understand all of the commands you may already know and add to them. Their purpose is to make the command line friendlier, easier to use, and much more powerful and versatile without requiring you to use or learn a new program, a new set of commands, or a new style of work. In this section, we introduce a few of the features we have built into our products. We don't have room to list them all or to explain all of the options available in each; that's what the Reference Manual and online help are for. This section will just give you a taste of what you can expect from your computer once you have your new command interpreter installed. As you read through this section, remember that you don't have to use any of these features except the ones that appeal to you. Learn just the parts that will make your computer easier for you to use, and add more features to your repertoire as you find that you need them. Built-In Commands 4DOS, 4OS2, and 4NT support every command you already know, add to the features of each command, and also add dozens of new commands. For example, the traditional DIR command, which displays a list of files, has about 8 options. The DIR command in our products has most of the same options plus almost 20 more. With the enhanced DIR command, you can: ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 9 Chapter 1 / Introducing 4DOS, 4OS2, and 4NT ------------------------------------------------------------------ * Display a list of files in 1, 2, 4, or 5 columns with the commands: c:\> dir c:\> dir /2 c:\> dir /4 c:\> dir /w * Use colors to indicate different kinds of files, display file descriptions (text to remind you of the contents of a file) along with file names, and sort files according to several different criteria. * Display hidden and system files, along with normal files. For example, this command displays all of the files in the current directory, whether they are "hidden" or not: c:\> dir /a * Display files of one type or of several types together. For example, this command lists all .TXT, .DOC, and .ASC files in the current directory: c:\> dir *.txt;*.doc;*.asc * Display files from a single directory, from one part of the directory tree, from a single drive, or from several drives. * Use wildcards to display all file names that start with the letter "A", end with the letter "A", or have an "A" anywhere in the name: c:\> dir a* c:\> dir *a c:\> dir *a* * If you use Windows 95 or Windows NT, you can view either "long" file names, "short" file names, or both. That's just an example of some of the enhancements we have added to one command. 4DOS, 4OS2, and 4NT have added enhancements to virtually every command you've used before and include dozens of new commands as well. You don't have to learn to use them all, but you will find many commands and enhancements that will make your computer more powerful and easier to use. For example: ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 10 Chapter 1 / Introducing 4DOS, 4OS2, and 4NT ------------------------------------------------------------------ * COLOR lets you set the default colors to use on your display: c:\> color bright white on blue Additional features let you customize the colors you want to use for parts of the display, for input and output, and for specific kinds of files. * LIST displays the contents of files in text or hexadecimal mode, lets you search a file, and can print either an entire file or a single page from a file: c:\> list readme.txt * FFIND searches for files based on their names and their contents. For example, to find all files on drive C: with the string "now" somewhere within their names: c:\> ffind /s *now* To find all .TXT files in the current directory which contain the string "then" somewhere in the file: c:\> ffind /t"then" *.txt * SELECT lets you pick the files you want to work with from a full-screen, "point and shoot" display. This command, for example, lets you select files from the current directory to copy to the floppy in drive A: c:\> select copy (*.*) a: * EXCEPT lets you work with all of the files in a directory except those that you want to exclude. It is something like wildcards in reverse. (A related feature, "exclude" ranges, also works like reverse wildcards, and can be used to exclude files from any internal command.) This command copies all files from the current directory to drive A: except backup (.BAK and .BK!) files: c:\> except (*.bak;*.bk!) copy *.* a: ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 11 Chapter 1 / Introducing 4DOS, 4OS2, and 4NT ------------------------------------------------------------------ The Command Line 4DOS, 4OS2, and 4NT are much more than just a collection of commands. They include a number of features which make the command line easier to use: * Interactive help appears whenever you ask for it and also any time you use a command incorrectly. Type: c:\> help when you need help. You can also press F1 to view the help Table of Contents. If you have typed part of a command, F1 displays help on the first word on the command line. * The command line works like a single-line word processor. You can edit any part of the line at any time before you press Enter to execute it or Esc to erase it. You can move the cursor left and right by a single character, a single word, or jump to the beginning or end of the line. You can delete, insert, or type over characters anywhere on the command line. * 4DOS, 4OS2, and 4NT keep track of each command you execute. You can display past commands, execute them again, or make changes before you execute them. The past commands can appear on the command line (if you press -), or in a pop-up window (if you press PgUp). * If you don't want to type a complete file name as part of a command, you don't have to. Just type part of the name and then press the Tab key: a matching file or directory name will appear on the command line. Press the Tab key again to see the next matching file. To choose from all matching files in a pop-up window, press F7 or Ctrl-Tab. The ability to complete filenames easily can be invaluable on a drive with long filenames _ all you have to do is type part of a lengthy file or directory name and press Tab. The command interpreter fills in the rest. * 4DOS, 4OS2, and 4NT keep track of each directory you have visited. There are many ways to return to previous directories; perhaps the easiest is to press Ctrl-PgUp to view past directories in a pop-up window. Select the directory you want, press Enter, ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 12 Chapter 1 / Introducing 4DOS, 4OS2, and 4NT ------------------------------------------------------------------ and you will immediately change to that directory, even if it is on a different drive. * Our programs also use an extended directory search "database" that will help you move, almost instantly, to any directory on any hard drive on your system when you type just part of the directory name. * Our command interpreters include features that let you select files by size, date, and time; to use multiple sets of wildcards at once; and to associate applications with their data files. For example, this command makes it simple to copy all files in the current directory that have been updated in the last week to a backup disk: c:\> copy /[d-7] *.* a:\ Or you can delete all .BAK files that are greater than 1 MB in size: c:\> del /[s1M] *.bak With a simple change you can make the command delete the same files, but from the entire drive rather than just the current directory (use a command like this with caution!): c:\> del /s /[s1M] *.bak * 4DOS, 4OS2, and 4NT let you associate file extensions with particular applications. For example, it's easy to start your word processor and load a letter anytime you type the name of an .LTR file: c:\> set .LTR=c:\wp\wordproc.exe After you have defined the association, you can start your word processor and have it load your letter to Mom, MOM.LTR, with this command (assuming the file is in the current directory): c:\letters> mom * You can also run multiple commands at one time. If you know the next 3 commands you need to run, you can type them all at once and then sit back while they are executed one at a time. For example, to copy all of your .TXT files to drive A: and then display the directory of drive A: ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 13 Chapter 1 / Introducing 4DOS, 4OS2, and 4NT ------------------------------------------------------------------ 4DOS c:\> copy *.txt a: ^ dir a: 4OS2, 4NT [c:\] copy *.txt a: & dir a: Configuration We don't know how you use your computer, or how you would like it to work, so we have made our programs as flexible as possible. With the included configuration utility you can configure almost every part of 4DOS, 4OS2, and 4NT to suit your needs or your whims. To start the configuration utility, type c:\> option For example, you can decide what colors to use for what purposes, how file names are displayed in command output, and command line editing details ranging from the size and location of pop-up windows to the shape of the cursor. 4DOS If conventional memory is tight on your DOS computer, you can configure 4DOS to squeeze out every last possible byte, using extended (XMS) memory, expanded (EMS) memory, upper memory blocks (UMBs), or conventional memory. In many installations, 4DOS uses just 256 bytes of conventional memory, leaving as much room free as possible for memory- hungry DOS application programs, memory-resident utilities, and games. Aliases and Batch Files We've left two of the most popular and powerful features, aliases and batch files, for last. Aliases Aliases are short sequences of commands which are stored in memory for very fast execution. Aliases can assign complex tasks to simple names or single keystrokes, define new commands, and set defaults for internal commands and for almost any application on your computer. They are the primary method we offer for customizing your command line to suit your needs. Here are a few examples of how you could define simple aliases to make the command line easier to use. The first two provide shorthand names for the DIR command _ D displays ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 14 Chapter 1 / Introducing 4DOS, 4OS2, and 4NT ------------------------------------------------------------------ a directory, and D2 displays a 2-column directory, sorted vertically, with a pause at the end of each page: c:\> alias d dir c:\> alias d2 dir /2pv Once these definitions have been entered, all you have to do is type D or D2 at the prompt to execute the corresponding alias. You can also define aliases as shorthand ways to execute applications, usually without having to add the application's directory to your PATH. For example, this alias allows you to just type EDIT to run your editor, even if its directory is not on the PATH: c:\> alias edit e:\edfiles\editor.exe You can put a whole group of commands into an alias so that you can invoke them without typing each one. This alias changes directories, runs the FINPROC program, and changes back to the original directory (the back-quotes [`] are used to enclose an alias when it contains more than one command). This alias should be entered on a single line: 4DOS c:\> alias monthly `pushd c:\monthly ^ finproc ^ popd` 4OS2, 4NT [c:\] alias monthly `pushd c:\monthly & finproc & popd` This short description explains only the basics of what aliases can do. Like most 4DOS, 4OS2, and 4NT features, aliases can be as simple or as complex as you like. You can save your aliases in a file and reload them each time the command interpreter starts (otherwise, you'd have to redefine them each time); assign aliases to keystrokes so they can be invoked quickly; write aliases which use other aliases; and use aliases within batch files. For complete information on aliases see Chapter 4 of the Reference Manual, the ALIAS command in Chapter 6 of the Reference Manual, or the online help. Batch Files A batch file or batch program is a text file that contains a list of commands to execute. 4DOS, 4OS2, and 4NT read and interpret each line as if it had been typed at the keyboard. If you're an experienced batch file programmer, or if you want an easy introduction to batch file programming, you ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 15 Chapter 1 / Introducing 4DOS, 4OS2, and 4NT ------------------------------------------------------------------ won't find anything more powerful than our built-in batch language. The batch language includes simple commands to display menus, boxes, lines, and colored text to dress up your batch file displays; a full range of user input commands; over 70 built- in variables that let your batch files test system configuration, device status, and free memory and disk space; and almost 100 built-in functions that let your batch files read from files, find the date, perform calculations, and manipulate strings. Our batch files run 2 to 10 times faster than traditional ones. They can include subroutines, loops, IF/THEN/ELSE logic, and even exception handling. And you can run them in single-step mode to debug them easily, learn exactly what each line does, or view changes to environment variables and other information as the batch file executes. Here are a couple of examples of simple batch files. The first example displays several pieces of information about your system status, using built-in variables provided with 4DOS, 4OS2, and 4NT: cls echo System status as of %_date at %_time: echo CPU: %_cpu echo Coprocessor: %_ndp echo Screen size: %_rows x %_columns echo Boot drive: %_boot echo DOS version: %_dosver echo Command processor version: %_4ver echo Country code: %_country The next example clears the screen, displays a short menu, accepts some input from the user, and displays the result (a more useful version of this file would actually perform the requested action; for now we're just trying to give you the overall flavor of our batch enhancements). The TEXT command displays a block of text on the screen, the SCREEN command positions the cursor, and the INKEY command accepts a single keystroke from the user: cls screen 5 0 text Choose an option: 1 - Word processing 2 - Spreadsheet 3 - Load the network ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 16 Chapter 1 / Introducing 4DOS, 4OS2, and 4NT ------------------------------------------------------------------ endtext screen +1 0 inkey Enter your selection: %%sel screen +2 0 echo You entered: %sel ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 17 Chapter 2 / Installation ------------------------------------------------------------------ Chapter 2 / Installation All copies of 4DOS, 4OS2, and 4NT come with automated software that makes installation simple and straightforward. The instructions for running this software vary depending on whether your copy came on a diskette or CD, or was downloaded from an on- line source. The installation software will set up the command interpreter automatically if you wish, and we recommend that you use this method. However, if you prefer to set up the program yourself you can allow the installation software to handle only certain required tasks (such as extracting files from a distribution disk), and perform the remaining steps manually. Manual installation is covered in detail for each product in Chapters 5 - 7. Preparing for Installation You can install and use each of our products under most recent operating system versions. If you are using an older version of any operating system, or you want to use a product under a different operating system than the one for which it is sold, consult Chapter 5, 6, or 7 (depending on the product) for details on compatibility before proceeding with installation. We strongly recommend that you install your new version of 4DOS, 4OS2, or 4NT in a new directory or folder, rather than using the same directory as a previous version, or a directory used by other software. 4DOS When installing 4DOS under Windows 95, we also strongly recommend that you use a short name for the 4DOS directory (i.e. a name where each element of the path uses more than eight characters for the name and three characters for the extension, with no white space or other special characters). If you install 4DOS in a directory with a long name, you will have to determine the equivalent short name and use it throughout the installation process. When you install your new command interpreter, some system files (e.g. CONFIG.SYS, AUTOEXEC.BAT, or your system registry) may need to be modified. You can allow the installation software to make these changes automatically, or you can make them yourself at a later time (see Manual Installation in Chapters 5 _ 7 for details). The Express ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 18 Chapter 2 / Installation ------------------------------------------------------------------ Installation option (see below) updates system files automatically; the Custom Installation option prompts you for confirmation before system files are updated. You will normally use a command or DOS prompt to begin the installation process. The command prompt can be run using the default command interpreter (COMMAND.COM or CMD.EXE) or a previous version of the product you are installing. If you are unsure of how to start a command prompt for installation, use these instructions: 4DOS If you are running plain DOS, just use your current DOS prompt. If you are running Windows or Windows 95, start an "MS-DOS prompt" session, or a 4DOS session if you have a previous version. If you are running OS/2, start a "DOS Window" or "DOS Full Screen" session from the Command Prompts folder. 4OS2 Start an "OS/2 Window" or "OS/2 Full Screen" session from the Command Prompts folder. 4NT Start an "MS-DOS Prompt" session, or a 4NT session if you have a previous version. You can also use your operating system's "start" mechanism, such as the Windows 95 Start button, to start the installation program directly. However, the instructions below assume you are working from a command prompt. Installing an Upgrade Use the standard installation instructions below to install an upgrade. The installation procedure is essentially the same as when you are installing a new copy of the program. If you are upgrading from a previous version, you may have a 4DOS.INI, 4OS2.INI, 4NT.INI, and / or 4START or 4EXIT files in the previous version's directory. To use these files with the new version, you must copy them to the new directory, and update the .INI file in some cases. You can allow the installation software to perform these steps automatically, or you can perform them yourself at a later time (see Chapters 5 _ 7 for details). Starting the Installation Software Our products are distributed using four standard methods: via electronic purchase, on a single-product diskette from JP ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 19 Chapter 2 / Installation ------------------------------------------------------------------ Software, on the JP CD Suite, or in a downloaded .ZIP file. Instructions for each format are below; be sure to follow the instructions which correspond to the way you obtained the program. If your copy of the program came from a collection of trial software on CD or diskette, and is stored in a .ZIP or other similar file, use the instructions which refer to a downloaded copy, even if you did not actually download the program. Installation of an Electronically Purchased Copy If your copy of 4DOS, 4OS2, or 4NT was purchased and delivered electronically (e.g., from the on-line ordering section of our web site), you can simply extract the downloaded files to a temporary directory, then start the INSTALL.EXE program. It will offer the same Express and Custom installation options described in the next section, and you can follow the directions for those options below. Installation from a JP Software Diskette or CD-ROM To begin the installation process, make sure you have a command or DOS prompt available (if you need instructions see Preparing for Installation above). Then start the installation program: * If you have a JP Software diskette, put the disk into drive A, then type this command at the prompt: a:install You can use drive B if you prefer, in which case you should substitute "b:" for "a:" in the command above. * If you have the JP CD Suite, put the CD into your CD-ROM drive, then type one of these commands at the prompt: d:\4dos\install d:\4os2\install d:\4nt\install where "d:" is the drive letter used for your CD-ROM. The installation software will offer two options: ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 20 Chapter 2 / Installation ------------------------------------------------------------------ * Express Installation will install the program automatically on your system and, as necessary, make appropriate modifications to CONFIG.SYS, AUTOEXEC.BAT, your current command processor startup files, and your system registry, without further prompting (except for required directory information). If you are installing the product under Windows 95, Windows NT, or OS/2, a new object will be created on the desktop to run the program. * Custom Installation will extract or copy the 4DOS, 4OS2, or 4NT files to your hard disk, then prompt you for confirmation before each installation step (including modifications to system files and the desktop). To install the program manually, use the Custom Installation option to extract or copy the necessary files, skip the steps you do not want performed automatically, and refer to the Manual Installation instructions in Chapters 5 _ 7. The diskette and electronic purchase installation programs also offer an Extract Individual Files option. This is used for restoring damaged files, and is not needed during a normal installation. It is not offered on the JP CD Suite, because no "extraction" process is necessary _ individual files can be copied with a simple COPY command. "Branding" If you received your copy of 4DOS, 4OS2, or 4NT on a JP Software diskette or CD-ROM, you will have a "brand card" or label with a serial number and validation code (in some cases you will have a separate card or label for each product). If your diskette or CD was purchased directly from JP Software the brand card will also include your registered name (company or individual). If your copy was purchased electronically the serial number and validation code are included in the materials you received as part of the purchase transaction. The serial number and validation code constitute your license, and are provided only with purchased copies, not with trial copies. A program which comes with each product checks your registered name, serial number, and validation code, and saves them for use by 4DOS, 4OS2, or 4NT. This process, ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 21 Chapter 2 / Installation ------------------------------------------------------------------ which we call "branding," personalizes your copy and removes the "unregistered copy" or other similar message which is displayed if you skip this step. Depending on the distribution mechanism used, some copies may not work at all until they are branded. The actual brand program name depends on the product (e.g. BR4DOS.EXE for 4DOS, etc.). The branding program is run automatically during the installation process. As you follow the instructions to enter your name, serial number, and validation code, be sure that all information is entered exactly as shown on the brand card, label, or electronic branding information you received. You cannot change spelling, capitalization, or punctuation. If you need to run the branding program manually, see the instructions in Chapters 5 _ 7. You may also need to run the branding program when you download a maintenance upgrade to any product. Branding a downloaded copy converts it from a timed trial copy to one fully registered to you. For this reason you should save your brand card, label, or electronically delivered branding information, in case it is needed when you download or purchase an upgrade. If you lose the branding information there is a charge to create a replacement card or label. Installation of a Downloaded Trial Copy To begin the installation process, make sure you have a command or DOS prompt available (if you need instructions, see Preparing for Installation above). Then: * Make sure you have extracted the files into a new directory using PKUNZIP or a similar utility. * At the prompt, change to the directory with your new copy of 4DOS, 4OS2, or 4NT. This step is essential. * Enter the name of the program you are installing at the prompt: C:\4DOS600> 4dos [C:\4OS2300] 4os2 [C:\4NT300] 4nt 4DOS, 4OS2, or 4NT will then run its installation procedure and set itself up for your system automatically. You can ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 22 Chapter 2 / Installation ------------------------------------------------------------------ allow the installation software to modify system files automatically, or modify them yourself at a later time. If you have an up-to-date copy of 4DOS, 4OS2, or 4NT, and have downloaded a maintenance upgrade, you may need to brand the new version with your registered name and serial number (see the previous section for details on branding). The automated installation procedure for the downloaded copy will start the branding program for you if possible. To brand a downloaded copy manually, see the instructions in Chapters 5 _ 7. If you try to brand a downloaded copy of a new major release, and you have not purchased a license for that release, the branding program will display a message indicating that you need to contact JP Software or your dealer for an upgrade. Once you have ordered an upgrade you can continue to use the downloaded trial version until your upgrade arrives. The automatic installation procedure for downloaded copies only runs the first time you start a new copy of 4DOS, 4OS2, or 4NT. If you need to re-install a downloaded copy, use the manual installation instructions in Chapters 5 _ 7. Uninstalling the Program We don't expect you to have trouble using our programs, but we know some people feel more comfortable knowing how to uninstall a product as well as install it. Or, you may need to remove the program from one system to move it to another system. To remove a purchased copy of 4DOS, 4OS2, or 4NT just insert the distribution diskette or CD, start the INSTALL program as described on page 19, and select the Uninstall option. Uninstall will offer you options which "undo" the corresponding steps in the installation procedure. Complete Uninstall will take all of the other steps automatically, and remove the program entirely from your system. The Uninstall option will attempt to reverse the changes made during installation, including modifications to your system files. However, if you have removed files, changed your directory structure significantly, moved COMMAND.COM or CMD.EXE, or otherwise modified your system configuration, then the program may not be able to complete all of the steps automatically and you will need to perform some of them manually. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 23 Chapter 2 / Installation ------------------------------------------------------------------ You will also need to uninstall the program manually if you installed it from a downloaded copy. See Chapters 5 _ 7 for instructions. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 24 Chapter 3 / The Help System ------------------------------------------------------------------ Chapter 3 / The Help System All of our products include complete online help. This chapter provides a basic description of how to use the help system, and lists important help topics you may want to refer to. Additional details are covered in the help system itself. If you need information on how to view the help text even when the corresponding product is not running, or additional information on configuring the help system for a specific product, see the details for your product in Chapters 5 _ 7. Using the Help System If 4DOS, 4OS2, or 4NT is running, you can start the help system by typing HELP (or HELP plus a command name) at the prompt, or by pressing the F1 key at any time at the command line. The information in each help system is fully cross- referenced, so you can move easily among related commands. If you type part or all of a command on the command line and then press F1, the help system will provide "context- sensitive" help by using the first word on the line as a help topic. If the first word is not a valid help topic you will see the Table of Contents (in 4DOS), or an error message (in 4OS2 or 4NT). For example, if you press F1 after entering each of the command lines shown below you will get the display indicated: c:\> Table of Contents c:\> copy *.* a: Help on COPY c:\> c:\util\map Table of Contents (4DOS); error (4OS2 or 4NT) If you type the name of any internal command at the prompt, followed by a slash and a question mark [/?] like this c:\> copy /? then you will see help for the command in a quick-reference style. Once you've started the help system, you can use a standard set of keystrokes or mouse actions to navigate through the help text. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 25 Chapter 3 / The Help System ------------------------------------------------------------------ Each help system can also be started "manually" (i.e., without the command processor running), and contains information which may be helpful if you encounter difficulties setting up 4DOS, 4OS2, or 4NT and configuring it for your system. See Chapters 5 _ 7 for details on starting the help system manually. Important Help Topics The help system includes documentation for all 4DOS, 4OS2, or 4NT commands and features. It also includes many other topics which may be of interest to you as you use the program or which you may need for advanced installations. This section lists some topics in the help system which you may find useful: * 4DOS.INI, 4OS2.INI, and 4NT.INI cover the .INI file, including reference information on all .INI directives. * Starting 4DOS, Starting 4OS2, and Starting 4NT (under Setup and Troubleshooting) explains the startup command line, and contain links to related topics like 4START and 4EXIT. * What's New explains changes in recent versions of 4DOS, 4OS2, or 4NT. Be sure to review this information before working with any upgrade. This section covers the current release and any prior releases of the same major version. For older historical information see our web site at http://www.jpsoft.com/. * Troubleshooting, Service, and Support (under Setup and Troubleshooting) includes a list of error messages and a discussion of useful diagnostic and troubleshooting techniques. It also contains information on contacting JP Software for technical support, sales, customer service, and other similar matters. * Reference Tables (under Reference Information) includes comprehensive lists of ASCII characters and keyboard codes. 4DOS * Compatibility discusses using 4DOS with products from other companies, including additional details on using 4DOS with Windows, Windows 95, and OS/2. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 26 Chapter 3 / The Help System ------------------------------------------------------------------ 4DOS * External (DOS) Help provides access to the MS-DOS / PC-DOS help system. This feature will only work if the 4DOS help program can find the DOS help program on your disk (see the External Help topic itself for details), and if the 4DOS help program has enough memory to execute DOS help. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 27 Chapter 4 / Configuration (All Products) ------------------------------------------------------------------ Chapter 4 / Configuration (All Products) Once you have 4DOS. 4OS2, or 4NT installed on your computer, the program is ready to run. However, you can configure each program in various ways to suit your needs and preferences. Most of the configuration or behavior of each program is controlled by aliases you create (explained in Chapter 4 of the Reference Manual, and in the online help) and by the .INI file (explained briefly below, and in detail in Chapter 5 of the Reference Manual, and in the online help). A few configuration options can also be set on the startup command line, which is explained here. In order to understand the startup command line you will also need to understand primary and secondary shells, so that topic is covered first. If you do not need to alter the startup behavior of 4DOS, 4OS2, or 4NT, you can skip the remainder of this chapter. If you are using our products under OS/2 or any flavor of Windows, we recommend that you read through this chapter, since each time you create a desktop object to run the command interpreter you will have to create a startup command line for that object. Primary and Secondary Shells 4DOS, 4OS2, and 4NT can be run as either primary or secondary shells. Under DOS, Windows 3.x, and Windows 95, a primary shell is started from the CONFIG.SYS file with a SHELL= command. Secondary shells are started when a program "shells" to the DOS prompt or runs a "transient" (temporary) shell to execute a specific command, or when you explicitly start a new shell from a desktop object under Windows 3.x or Windows 95. Under OS/2 and Windows NT, a primary shell is started each time you start a new command-line session or window from the desktop. A secondary shell is started when a program "shells" to the command prompt, or runs a "transient" (temporary) shell to execute a specific command. Whenever you start a primary or secondary shell, you can control the way that 4DOS, 4OS2, or 4NT starts by adjusting the startup command line. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 28 Chapter 4 / Configuration (All Products) ------------------------------------------------------------------ Command Line Options A few of the command-line switches or options that 4DOS, 4OS2, and 4NT recognize are required in certain circumstances; most others are needed only if you want finer control over the way the program starts. The line that starts 4DOS, 4OS2, or 4NT will typically include the program name with drive and path, optionally repeat the name of the directory where the program is stored, and finally include any switches for the program, for example: e:\4dos600\4dos.com e:\4dos600 /p This command line may appear on its own (for example, in a Windows or OS/2 desktop object), or in an operating system directive (e.g. the SHELL command in the DOS, OS/2, or Windows 95 CONFIG.SYS file). Specific details on where you should enter the command line for each product are included in Chapters 5 _ 7. Although the startup command line is usually very simple, you can add a number of options if you need to customize the way the command interpreter starts. The complete syntax for the startup command line is: d:\path\program [d:\path] [@d:\path\inifile] [//iniline] [/D /E:nnnn /F /L /LA /LD /LH /P[:filename] /Q /S /T:bf /X /Y] [[/C | /K] command] Do not include the square brackets shown in the command line above. They are there to indicate that the items within the brackets are optional. Not all options are available in all products; see below for details. If you include any of the options below, you should use them in the order that they are described. If you do not do so, you may find that they do not operate properly. The following items can be included on the command line: * d:\path\program: The path and name of the executable program file (4DOS.COM, 4OS2.EXE, or 4NT.EXE). It is required to start 4DOS, 4OS2, or 4NT. * d:\path: This is the second d:\path in the command line above. It sets the drive and directory where the program is stored, called the COMSPEC path. 4DOS, 4OS2, and 4NT use this path to find their files ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 29 Chapter 4 / Configuration (All Products) ------------------------------------------------------------------ and to set the COMSPEC environment variable (see your Reference Manual or online help for more information on COMSPEC). 4DOS Under 4DOS, this option is generally required for the primary shell, but not for secondary shells. In some cases the primary 4DOS shell can find its directory automatically and this option is not needed, but we recommend that you use it on all primary shells to ensure that the directory is found. If you are running Windows 3.x or Windows 95 and you do not load 4DOS as the primary shell in CONFIG.SYS, you must use this option in each desktop object or shortcut command line to allow 4DOS to find its files. 4OS2, 4OS2 and 4NT normally know what drive and directory 4NT they are started from, so this option is not usually necessary. * @d:\path\inifile: This option sets the path and name of the .INI file. You don't need this option if you aren't using an .INI file at all, or if the file has the default name (4DOS.INI, 4OS2.INI, or 4NT.INI) and it is either in the same directory as the executable program or in the root directory of the boot drive. This option is most useful if you want to start the program with a specific and unique .INI file. * //iniline: This option tells 4DOS, 4OS2, or 4NT to treat the text appearing between the // and the next space or tab as an .INI directive. The directive should be in the same format as a line in the .INI file, but may not contain spaces, tabs, or comments. Directives on the command line override any corresponding directive in the .INI file. This option may be repeated. It is a convenient way to place a few simple directives on the startup line without having to modify or create a new .INI file. 4DOS * /D: In 4DOS only, this option disables execution of AUTOEXEC.BAT (or the file named in the AutoExecPath directive in 4DOS.INI). It is intended for internal use by MS-DOS / PC-DOS 6.x and 7.x (including Windows 95). When you press the F8 key during the boot process, MS-DOS prompts for whether to run AUTOEXEC.BAT. If you answer "No", the /D switch is used to relay your choice to 4DOS. This option is not available in 4OS2 or 4NT. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 30 Chapter 4 / Configuration (All Products) ------------------------------------------------------------------ 4DOS * /E:nnnn: In 4DOS only, this option sets the size of the environment in bytes. If you don't use this option, 4DOS will allocate 512 bytes for the environment. You can use any value from 256 to 32000 as the environment size. For example, to set an environment of 1,000 bytes, you would enter the option as /E:1000. You can also set the environment size with the Environment directive in the 4DOS.INI file (see your Reference Manual or online help). We recommend that you use the directive instead of the /E switch, so that all configuration information is kept in one place in the 4DOS.INI file. 4OS2, 4OS2 and 4NT allocate space in the environment 4NT dynamically instead of using a fixed amount of space. Therefore, this option is not available in either program. 4DOS * /F: This option tells 4DOS to automatically provide a Fail response to all critical errors, without prompting or waiting for a user response. It is rarely used except on systems that must run unattended, like bulletin boards. We do not recommend use of this option on a normal system, because you will not have a chance to react to a critical error and correct the problem that caused it. For more information on critical errors see Chapter 3 of your Reference Manual, or the online help. /F only affects critical errors detected by 4DOS, and will not affect critical error handling for many application programs which perform this function themselves. It is equivalent to the directive CritFail=Yes in 4DOS.INI. The /F option is not available in 4OS2 or 4NT. * /L, /LA, /LD, and /LH: These options force 4DOS, 4OS2, or 4NT to use a local alias, directory history, and / or command history list. They can be used to override any LocalAlias=No, LocalHistory=No, or LocalDirHistory=No settings in the .INI file. This allows you to use global lists as the default, but start a specific shell or session with local aliases or histories. See your Reference Manual or online help for details on local and global aliases and histories. /LA forces local aliases, /LD forces local directory history, /LH forces local command ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 31 Chapter 4 / Configuration (All Products) ------------------------------------------------------------------ history, and /L forces all three _ local aliases, command history, and directory history. 4DOS * /P[:filename]: This option tells 4DOS to load permanently and to run AUTOEXEC.BAT. If you specify a filename after the /P, that file will be run instead of AUTOEXEC.BAT. You should specify the full name of the file, including drive and directory. A filename after /P will override the AutoExecPath option in 4DOS.INI. When 4DOS is loaded from the SHELL= command in CONFIG.SYS, or as the shell for an OS/2 DOS session, it will normally detect that it is the primary shell and set the /P option automatically. Under very rare circumstances, you may want to load 4DOS permanently and have it run AUTOEXEC.BAT even though you are not loading it from CONFIG.SYS; in such cases you must set /P yourself. 4DOS will not run AUTOEXEC.BAT without either an automatic or an explicit /P. Do not use this option in secondary shells, or you will be unable to return to the primary shell. The /P option is not available in 4OS2 or 4NT. 4NT * /Q: This option, which is only available in 4NT, has no effect. It is included only for compatibility with CMD.EXE. 4NT, * /S: This option tells 4OS2 or 4NT that you do not 4OS2 want it to set up a Ctrl-C / Ctrl-Break handler. It is included for compatibility with CMD.EXE, but it may cause the system to operate incorrectly if you use this option without other software to handle Ctrl-C and Ctrl-Break. This option should be avoided by most users. It is not available under 4DOS. 4NT * /T:bf: This option sets the foreground and background colors in the 4NT window. Both b and f are hexadecimal digits; b specifies the background color and f specifies the foreground color. This option is included only for compatibility with CMD.EXE; in most cases you should set default colors with the StdColors directive in 4NT.INI, or the corresponding Output Colors option on the Display page of the OPTION command's configuration dialogs. 4NT * /X: This option forces 4NT to alter the operation of the MD and MKDIR command to automatically create all necessary intermediate directories when it creates a ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 32 Chapter 4 / Configuration (All Products) ------------------------------------------------------------------ new subdirectory. Its effect is the same as adding a /S option to all MD and MKDIR commands (see the Reference Manual or online help for details about the MD /S command). This option is included for compatibility with CMD.EXE. In CMD.EXE it enables other options as well, but in 4NT the only option not enabled by default is the implicit MD /S. 4DOS * /Y: This option forces 4DOS to enable the batch file debugger for 4START and AUTOEXEC.BAT (or the file named in the AutoExecPath directive in 4DOS.INI). It is intended for internal use by MS-DOS / PC-DOS 6.x and 7.x (Windows 95). When you press the F8 key to enable single-stepping during the boot process and then elect to single-step through AUTOEXEC.BAT, the /Y switch is used to relay your choice to 4DOS. This option is not available in 4OS2 or 4NT. * [/C | /K] command: This option tells 4DOS, 4OS2, or 4NT to run a specific command after starting. The command will be run after 4START, and after AUTOEXEC.BAT in a 4DOS primary shell. The command will be run before the prompt is displayed. The command can be any valid alias, internal or external command, or batch file. All other startup options must be placed before the command, because the command interpreter will treat characters after the command as part of the command and not as additional startup options. When the command is preceded by a /C, 4DOS, 4OS2, or 4NT will execute the command and then exit and return to the parent program or the desktop without displaying a prompt. This is sometimes called a "transient" command interpreter session. In 4OS2 and 4NT, and in 4DOS when it is started as a secondary shell (for example from the Windows desktop), the /K switch has no effect; using it is the same as placing the command (without a /C or /K) at the end of the startup command line. It is included only for compatibility with COMMAND.COM and CMD.EXE. 4DOS When you start 4DOS from the SHELL= line in MS-DOS / PC-DOS 6.x and use /K, the command will be executed instead of AUTOEXEC.BAT (for compatibility with MS- DOS / PC-DOS 6.x COMMAND.COM). This behavior occurs only in MS-DOS / PC-DOS 6.x, not in other DOS versions or in Windows 95. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 33 Chapter 4 / Configuration (All Products) ------------------------------------------------------------------ For example, this command line will start 4DOS, execute any 4START file you have created, execute the file START.BTM, and then display the prompt: c:\4dos600\4dos.exe c:\4dos600\start.btm This command line will start 4OS2, select local aliases, execute any 4START file you have created, execute the file PROCESS.BTM, and then exit when PROCESS.BTM is done. The prompt will not be displayed by this session: c:\4os2\4os2.exe /la /c c:\4os2\process.btm Creating or Modifying Startup Files Each of our products uses two files to control the way it starts: a file of configuration information called the .INI file (named 4DOS.INI, 4OS2.INI, or 4NT.INI), and a startup batch file called 4START (depending on your operating system, 4START may have the extension .BTM, .BAT, or .CMD). The .INI file is optional, except in 4DOS (see page 39 for details). A small default .INI file may be created during the installation process in some cases. The .INI file for each command processor should be placed in the same directory as the other files for that product. You can add additional information to the .INI file manually with an ASCII editor, or you can use the OPTION command to aid you in selecting configuration options. The 4START file is also optional. It is executed each time 4DOS, 4OS2, or 4NT starts, and gives you a convenient way to load aliases and environment variables, and otherwise initialize the command processor _ especially under 4NT and 4OS2, which do not use an AUTOEXEC.BAT file. 4START is normally placed in the same directory as the other product files, but this may vary if you use the same 4START file for more than one product. For complete details on startup files, on the OPTION command, and on the 4EXIT file (executed when the command processor exits), see your Reference Manual or the online help. If you are upgrading from a previous version of 4DOS, 4OS2, or 4NT, you may have a .INI file and / or a 4START (or 4EXIT) file in the previous version's directory. To use these files with your new version, you must copy them to the new directory, and then update any paths in either file which point to the old program directory. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 34 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ Chapter 5 / 4DOS Configuration and Notes 4DOS works well with virtually all PC hardware; with a wide range of operating systems and environments, including MS DOS, PC-DOS, Novell DOS / OpenDOS, Windows 3.x, Windows 95, and OS/2 (see page 1 for a complete list); and with all DOS-based, Windows-based, and OS/2-based networks. Each environment makes different demands on 4DOS and the user. 4DOS is not recommended for use under Windows NT, or supported in that environment. If you are running Windows NT, use our 32-bit Windows NT command interpreter, 4NT. This chapter provides the basic information you need to run 4DOS in any of the standard PC environments. If you need more detailed technical information or troubleshooting assistance on any of these topics, consult the Troubleshooting, Service, and Support and Compatibility topics in the 4DOS online help. If you are running under DOS and do not use Windows, Windows 95, OS/2, or a network, you can safely skip this chapter, and return to it only if you have difficulty with 4DOS or questions about how it interacts with other software. 4DOS Installation Notes When you install 4DOS, your CONFIG.SYS and AUTOEXEC.BAT files must be modified. You can allow the installation software to make these changes automatically, or you can make them yourself at a later time (see Manual Installation of 4DOS below for details). When installing 4DOS under Windows 95, we also strongly recommend that you use a short name for the 4DOS directory (i.e. a name where each element of the path uses more than eight characters for the name and three characters for the extension, with no white space or other special characters). If you install 4DOS in a directory with a long name, you will have to determine the equivalent short name and use it throughout the installation process. If you install 4DOS under Windows 95, the installation program will create a Start menu group for JP Software products, including 4DOS. In addition, a small group of entries will be added to the system registry (if you allow such modifications); for more details see page 47. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 35 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ If you install 4DOS in an OS/2 DOS session, the OS/2 CONFIG.SYS and AUTOEXEC.BAT files will be modified to use 4DOS as your default command processor for OS/2 DOS sessions (if you allow such modifications). Installing 4DOS does not modify, remove, or otherwise alter any of your other system files. Older Versions of DOS If you're running DOS 5 or earlier, we recommend that you make a bootable system diskette before you install 4DOS (or any other software, for that matter). This allows you to recover in case of a power failure, error, or other interruption during the installation process. See your DOS documentation for details about creating a bootable floppy disk. In DOS 6 and above and in Windows 95, a bootable disk usually is not necessary because the F5 and F8 keys can be used to skip steps in the boot process and recover from errors in configuration files. In OS/2, a bootable disk usually is not necessary because the operating system will boot normally whether the DOS command interpreter is completely installed or not. Manual Installation of 4DOS This section is for advanced users, and assumes you are generally familiar with CONFIG.SYS, AUTOEXEC.BAT, and other concepts such as ASCII editors and batch files. In most cases, manual installation is not necessary because you can select the installation options you need using the automated installation program. In order to install 4DOS manually, you must extract or copy the necessary files, brand 4DOS if necessary, create or modify any configuration files you need, and then create the necessary commands to start the program on your system. Extracting or Copying the Program Files When you extract or copy the 4DOS files, be sure to place them in their own directory, rather than using the same directory as a previous version of the program, a directory used by other JP Software products, or a directory used by other software. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 36 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ We strongly recommend that you place all of the 4DOS files in the same directory. See 4DOS Files and Directories on page 40 for some important considerations if you choose not to follow this recommendation. The method used to extract or copy the files depends on how you obtained your copy of the program: * If you have a JP Software diskette you must use the installation program to extract the files, which are compressed on the distribution disk. You cannot simply copy the files onto your hard disk. Select Custom Install and follow the prompts to specify the installation directory and copy the files. Then exit the installation program with Ctrl-X, or answer No when prompted for whether to proceed with each additional step. * If you have a copy purchased electronically you must use the installation program to extract the files as described above. First extract the installation files from the compressed file you downloaded into a temporary directory, then run the INSTALL program. Use the Custom Install option as described in the preceding paragraph. * If you have the JP CD Suite, all of the files are stored uncompressed on the CD, in the \4DOS directory, and you can copy them manually if you wish. However, we still recommend that you use the installation program to copy the files. Some files may be renamed after copying, and some files are used only during the installation process and do not need to be copied to your hard disk. If you copy the files manually, a few may not have the correct names, and you may copy more files than you need, resulting in wasted hard disk space. * If you have a downloaded trial copy of the program, or a copy distributed on a CD or diskette of trial software, extract the files into a new directory using the appropriate decompression program (e.g. PKUNZIP). "Branding" 4DOS (If you are not familiar with branding, refer to the general information on page 21 before continuing with this section.) ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 37 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ If you have purchased a copy of 4DOS the automated installation procedure will normally run the BR4DOS program to check your name, serial number, and validation code and "brand" 4DOS as a registered product (in some cases 4DOS may not operate properly until this step is completed). If you need to brand 4DOS manually, go to a 4DOS or COMMAND.COM prompt, change to the directory where 4DOS is stored, and enter the command: c:\4dos600> br4dos Follow the instructions displayed by BR4DOS to enter your name, serial number, and validation code. All information must be entered exactly as shown on your original brand card, label, or electronically delivered branding information; you cannot change spelling, capitalization, or punctuation. Updating CONFIG.SYS and AUTOEXEC.BAT (Please Note: If you installed 4DOS to a directory with a long name under Windows 95, you must determine the equivalent short name for use when updating CONFIG.SYS and AUTOEXEC.BAT. Paths in these files can not be entered in long name form.) When you're ready to finish installing 4DOS, you need to add one line to your DOS, Windows 95, or OS/2 CONFIG.SYS file: SHELL=d:\path\4DOS.COM d:\path /P "d:\path" means the drive and directory where 4DOS.COM is stored. The second "d:\path" on the SHELL= line should be the same as the first, and is used to set the COMSPEC environment variable properly. Be sure to delete or REMark out any old SHELL= line for COMMAND.COM after you add the new SHELL= line for 4DOS. You can add any command line options to the end of the line. See Chapter 4 on page 28 for information on command line options. If you are running 4DOS under DOS 4.01 or earlier, you must make sure that the portion of the SHELL= line beginning with the second "d:\path", through the end of the line, does not exceed 31 characters, due to a bug in DOS. For details, see the Compatibility section in the online help. If you are running 4DOS under OS/2, change CONFIG.SYS as described above (don't forget to find and REMark out or delete the old SHELL= line). Once you reboot, 4DOS will be ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 38 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ used automatically for all DOS objects which use the default DOS_SHELL settings. See page 50 for more details on configuring OS/2 DOS sessions to use 4DOS. Next, if you are running under DOS, OS/2, or Windows 3.x, add the following line to your AUTOEXEC.BAT file: d:\path\KSTACK.COM where "d:\path" is the drive and directory where your 4DOS files are stored. KSTACK.COM is a memory-resident program used to support the KEYSTACK command. It requires about 1K of memory, and can be left out of AUTOEXEC.BAT if you do not use KEYSTACK. Do not add the KSTACK line to AUTOEXEC.BAT if you are using Windows 95. Under Windows 95, KSTACK should be loaded separately for each 4DOS session; see page 48 for details. If you have a line in AUTOEXEC.BAT which sets the COMSPEC environment variable to point to COMMAND.COM, remove it or REMark it out. If you set up the CONFIG.SYS file properly, 4DOS will set this variable automatically; setting it in AUTOEXEC.BAT is likely to cause trouble later on (for example, if you install an update to 4DOS in a different directory, but forget to change the COMSPEC setting). If you have a line in AUTOEXEC.BAT which copies COMMAND.COM to a RAM disk for faster reloading when an application program ends, remove it or REMark it out. Using a similar command with 4DOS is not necessary; see the Swapping directive in Chapter 5 of the Reference Manual, or in the online help, for details about how 4DOS reloads itself. When you've finished modifying CONFIG.SYS and AUTOEXEC.BAT, you can reboot your system to start 4DOS. Creating or Copying 4DOS.INI (For general information on the .INI file see page 34.) 4DOS requires a 4DOS.INI file with at least one line in it: InstallPath = d:\path where "d:\path" is the drive and directory where your 4DOS files are stored (under Windows 95, this must be the short name of the directory; long names cannot be used). This will help 4DOS locate its auxiliary files, such as the help files ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 39 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ and OPTION.EXE. The automated installation process always places this line in 4DOS.INI. If you need to create the file manually, you can do so with any ASCII file editor. The InstallPath setting should be the first line in the file. If you are upgrading from a previous version of 4DOS, you should copy any 4DOS.INI file you have in the old directory to the new one. Then add or modify the InstallPath directive at the beginning of 4DOS.INI, remove any HelpPath directive in the file (HelpPath is obsolete and has been replaced by InstallPath), and update any paths in the file which point to the old program directory (e.g. 4StartPath). 4DOS Files and Directories We strongly recommend that you place all 4DOS files in the same directory. If you do not do so, you will have to explicitly set the locations of 4DOS files to avoid problems. You may feel that you should place 4DOS.COM in the root directory because it is a system-related file. We do not recommend this practice; 4DOS will run just fine from its own directory, and keeping it there makes configuration much simpler. If you do wish to move files to different directories, the following information will help you set up the programs correctly: 4DOS.COM is the 4DOS program file. It must be in the directory specified by the SHELL= line in your DOS, Windows 95, or OS/2 CONFIG.SYS file, or the directory specified on the command line in every desktop object used to start 4DOS. 4HELP.EXE is the 4DOS help program. For online help to work, this file must be in the 4DOS installation directory shown in the InstallPath directive in 4DOS.INI, or in a directory included in your PATH. 4DOS.HLP contains the text for the 4DOS help program. It must be in the same directory as 4HELP.EXE, or in a directory included in your PATH. KSTACK.COM is the used by the KEYSTACK command. If you wish to use the KEYSTACK command, this file should be loaded in your AUTOEXEC.BAT file (under DOS, Windows 3.x, and OS/2) or separately for each 4DOS session (Windows 95). This file does not have to be in the 4DOS ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 40 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ directory. If KSTACK.COM has not been loaded, you will see an error message when you attempt to use the KEYSTACK command. OPTION.EXE is a utility used by the OPTION command to configure 4DOS. For the OPTION command to work, this file must be in the 4DOS installation directory shown in the InstallPath directive in 4DOS.INI, or in a directory included in your PATH. The 4DOS Help System The 4DOS help program is called 4HELP.EXE; the help text is stored in the file 4DOS.HLP. The 4DOS help system provides complete help for 4DOS commands and features; on most systems it can also launch the DOS help program to display help on external DOS commands like FORMAT or SORT. The section entitled The 4DOS Help System within the help system itself explains navigation keystrokes and mouse usage in more detail, as well as instructions on linking the help system to DOS help or other help programs. If you do not have 4DOS running, you can start the help system by moving into the directory that contains your 4DOS files (we assume that you are using C:\4DOS600 in this example) and typing this command: C:\4DOS600> 4help You can use this command if you are unable to install 4DOS completely for some reason; information in the help system will likely help you solve the problem. 4OS2 also supports the /? switch to display help for any command. Using /? will display brief help text for the command within the 4OS2 window. 4DOS and Your Computer 4DOS will work on any IBM PC-compatible hardware, regardless of the CPU type, amount of memory (assuming the minimum 256K or so required to run 4DOS is available), disk configuration, or video hardware. The notes below briefly cover memory, video, and disk issues. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 41 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ Memory 4DOS knows how to use XMS memory, EMS memory, and Upper Memory Blocks (UMBs) in order to minimize the amount of space it takes in the 640K of DOS memory available to your application programs. You can control 4DOS's memory usage with directives in the 4DOS.INI file. For more details about configuring 4DOS's memory usage see Initialization Directives under .INI File Directives in the 4DOS.INI section of the online help. You can also set most memory usage options easily from the Startup page of the OPTION command's dialogs. By default, 4DOS uses normal DOS memory ("low memory") for its small resident portion of about 3 - 4K. 4DOS can reduce its low memory usage by moving most of this information to Upper Memory Blocks (UMBs), when requested with UMBLoad and other UMB-related directives in the 4DOS.INI file. Low memory is also used to hold the larger (about 200K) transient portion of 4DOS while your system is at the prompt, or executing an internal 4DOS command or batch file. When an external application is running 4DOS moves its transient portion to EMS or XMS memory (or the hard disk), so the memory is available to the application. For additional details see the Reference Manual or online help, and in particular the documentation on the Swapping directive in 4DOS.INI. Video 4DOS can normally adjust itself to your video hardware automatically, regardless of your video adapter and the number of rows and columns on your screen. Most video problems turn out to be unrelated to 4DOS, and are often due to the underlying operating environment (for example, attempting to display blinking text in a window when the underlying environment does not support this feature). If you experience scrolling or color problems, you should also check whether you have an ANSI driver installed, and if so verify that it is configured correctly and can support your video hardware. Disk Drives 4DOS supports all types of disks including floppy disks, hard disks, high-capacity removable disks, compressed drives, ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 42 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ network drives, and RAM disks. 4DOS never directly modifies the FAT, root directory, subdirectories, or other system areas of the disk, and it doesn't write any data on your disk itself. It always calls on DOS to perform these actions, just like most application programs do. As a result, 4DOS is compatible with all disk sizes, formats, and structures that your DOS version supports. If you receive unexpected results related to a disk drive or disk file (for example, an apparent error in the amount of free space on a drive, or an "access denied" message when attempting to use a file you thought was available), chances are that 4DOS is merely reporting information provided by the operating system, and is not the original source of the problem. 4DOS and DOS 4DOS is compatible with MS-DOS or PC-DOS 3.1 and above, DR DOS / Novell DOS / OpenDOS 3.4 and above, Windows 95 (and its built-in version of DOS, "MS-DOS 7"), and OS/2 DOS sessions. See page 45 for additional important information on Windows 95, and page 50 for information on OS/2. More detailed information on 4DOS and DOS is covered in the Compatibility section of the online help. If you use any of the DOS versions or features listed below, you may want to check that topic for additional information. This is only a partial list of the DOS-related items discussed in the online help. Inclusion of an item here does not mean it is incompatible with 4DOS, but only that more information on it is available in the help system. The help system includes information you may need if you use: * Any version of DR DOS, Novell DOS, or OpenDOS. * Utilities which allow multiple configurations in your DOS CONFIG.SYS file, including the MS-DOS or Windows 95 multiple configuration feature. * The MS-DOS APPEND utility. * The FORMAT /S and SYS commands (used to create a bootable floppy disk) under MS-DOS or PC-DOS version 4.0 or above. * The DBLSPACE and DRVSPACE disk compression utilities. * The MS-DOS 6.x and Windows 95 HELP command. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 43 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ * The FASTOPEN utility. * The MS-DOS 6.x and Windows 95 MOVE command. * The MS-DOS / PC-DOS 6.x SMARTDRV disk cache. 4DOS and Microsoft Windows 3.x This section applies to Microsoft Windows 3.x, including Windows for Workgroups. See the next section for information on Windows 95. For additional details on using 4DOS with Windows see the Compatibility section in the online help. 4DOS works well as both the primary shell, loaded before Windows, and as a secondary shell loaded inside any window. It works in both Standard and Enhanced modes. If you plan to run 4DOS under Windows we strongly recommend that you install it as the primary shell in CONFIG.SYS (this is the way 4DOS is normally installed). If you do not install 4DOS as the primary shell, individual 4DOS sessions will not be able to share global alias, command history, and directory history lists; each 4DOS session will have to process the .INI file before it starts; and, if you have two or more 4DOS sessions running simultaneously from the Windows desktop, they will use more system resources than they would if 4DOS were installed as the primary shell. To run 4DOS from within Windows, you will need to create a new "4DOS" item on your Program Manager desktop. The generic "MS-DOS Prompt" item supplied by Microsoft runs COMMAND.COM; we recommend that you leave this icon's properties unchanged, and create a new item for 4DOS. You can set up a 4DOS item from the Program Manager's File / New menu selection. To do so, simply create a new program item and set the command line to d:\path\4DOS.COM (use the appropriate drive and path for your system). Use the Change Icon button to assign the standard 4DOS icon, in the file 4DOS.ICO, to the shortcut (use 4DOSM.ICO for monochrome displays). You can put command-line switches, a command, or the name of a batch file at the end of the command line for any 4DOS item. This allows you to run specific commands or set configuration options when you start 4DOS from that item. However, no additional settings are required; the only required item is the drive and path for 4DOS.COM. For details on the command line options available for 4DOS items ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 44 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ see Chapter 4, and the Starting 4DOS section of the online help. If you use an alternate Windows shell, such as Norton Desktop for Windows, see the documentation for your shell to determine how to set up a new desktop object and assign an icon to it. For more flexibility, you can use the Windows PIF editor to create or modify a 4DOS.PIF file. We have included a sample .PIF file on the distribution diskette. You must modify this file and make it correspond to your system configuration, including the directory that contains 4DOS, before you use it. 4DOS and Microsoft Windows 95 This section provides basic information on using 4DOS under Windows 95. For additional details see the Compatibility section in the online help. 4DOS works well as both the primary shell, loaded before Windows 95, and when loaded from the Windows 95 GUI. If you are using 4DOS under Windows 95, we strongly recommend that you install it as the primary shell in CONFIG.SYS (this is the way 4DOS is normally installed). If you do not install 4DOS as the primary shell, individual 4DOS sessions will not be able to share global alias, command history, and directory history lists; each 4DOS session will have to process the .INI file before it starts; and, if you have two or more 4DOS sessions running simultaneously from the Windows 95 desktop, they will use more system resources than they would if 4DOS were installed as the primary shell. If you have a typical Windows 95 configuration, and install 4DOS as the primary shell, generally you must have an AUTOEXEC.BAT file, even if it only consists of a single REM statement. In most cases Windows 95 will not load the primary shell if it cannot find an AUTOEXEC.BAT file in the root directory of your Windows 95 boot drive. Installing 4DOS Under Windows 95 The 4DOS installation program will install and configure 4DOS correctly for Windows 95. If you are installing 4DOS manually, follow the instructions under Manual Installation on page 36. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 45 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ If you reinstall Windows 95, your SHELL= line will be removed from CONFIG.SYS by the Windows 95 installation process. To correct this, simply boot the new version and use Notepad or another ASCII editor to put the SHELL= line back in CONFIG.SYS as described in the manual installation instructions on page 36, then restart Windows 95. If you load Windows 95 in "safe mode" your startup files (CONFIG.SYS and AUTOEXEC.BAT) are ignored, and 4DOS will not be loaded as the primary shell. When you start Windows 95 in "safe mode," in most cases you should NOT load 4DOS after the GUI starts. DOS applications often do not work properly in "safe mode." Creating 4DOS Shortcuts When 4DOS is installed it normally creates a JP Software program group which appears on the Start Menu under Programs, and includes items to start 4DOS and its online help. The installation program also creates a desktop shortcut for 4DOS. These entries are created based on the file JPSOFT.INF, which is distributed with Take Command. If you have a downloaded trial copy of 4DOS, JPSOFT.INF will not be installed automatically; if you want to install it you must do so manually. See the comments below and in the file for additional details. If you need to create a similar program group or shortcuts manually _ for example, if the JP Software group on the Start menu is inadvertently damaged or deleted _ you can use the Windows Explorer's facilities for creating shortcuts and modifying the desktop and / or the Start menu (see below). You can also install JPSOFT.INF manually if you wish; see the comments in the file for details. JPSOFT.INF is designed to install JP Software's 4DOS, 4NT, and Take Command/32 products under Windows 95 and Windows NT. It will install the product stored in the directory from which JPSOFT.INF is run; the entries for other products and operating systems will be ignored. To remove the desktop shortcuts and group created by JPSOFT.INF, open the Windows Control Panel and select Add / Remove Programs. Select the item listed as "JP Software program shortcuts (remove shortcuts and group)" and click the Add / Remove button. The JP Software group and all of its entries will be removed without further prompting. (To remove only the entries for a single product, use the Windows ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 46 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ Explorer.) The removal operation may not work correctly if you modified the group or shortcuts manually after they were created. If you want to create additional shortcuts elsewhere on the Start menu, or modify the Programs entries, click mouse button 2 in an open area of the Task Bar, and select Properties on the popup menu. Select the Start Menu Programs tab and modify or adjust the menus as required. You can also manually create one or more shortcuts on the desktop to run 4DOS. To do so click with mouse button 2 in any open area of the desktop. On the popup menu click New, then Shortcut. Fill in the drive and path as d:\path\4DOS.COM (use the appropriate drive and path for your system). Add any other command line options you wish to set to the end of the line. You can also put command-line switches, a command, or the name of a batch file at the end of the command line for any shortcut. This allows you to run specific commands or set configuration options when you start 4DOS from that shortcut. For details on the command line options available, see Chapter 4 and the Starting 4DOS section of the online help. For more information on creating and configuring shortcuts or modifying the Start Menu, see your Windows 95 documentation. Windows 95 Registry Extensions for 4DOS JP Software distributes a file of registry extensions for 4DOS, for use under Windows 95 (for information on registry changes for the Start menu and desktop shortcuts, see the previous section). The registry extensions are stored in the file JP4DOS.INF. Installing these extensions will: * Designate 4DOS .BTM files (enhanced batch files) as batch files. They will then be recognized as such by the Windows Explorer; * Provide an additional "open" option in the context (mouse button 2) menu of all batch files, to explicitly run the file with 4DOS; and * Create a new entry in the context menu of drives and directories to launch 4DOS in that drive / directory. You will have the option to install JP4DOS.INF automatically during the 4DOS installation process. You can also install ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 47 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ it manually by opening the 4DOS directory from within the Windows Explorer, clicking on JP4DOS.INF with mouse button 2, and selecting INSTALL from the popup menu. If you have a downloaded trial copy of 4DOS, JP4DOS.INF will not be installed automatically; you must use manual installation. See the comments in the file for additional details. JP4DOS.INF assumes that you have a relatively standard system configuration. If you have modified basic items in your registry (such as the characteristics of the system file type "batfile"), the registry extensions may not work correctly. To adjust the registry entries made when you install JP4DOS.INF, open the Windows Explorer, and select Options on the View menu. Click on the File Types tab and find the listing for batch files (typically under "MS-DOS Batch File"). Use the Edit button to adjust this listing. JP4DOS.INF also makes minor changes to the Drive and Directory types; you may want to modify these as well. Note that some of these file types may not be editable on your system, depending on the settings of various edit flags in the registry. To remove the registry entries created by JP4DOS.INF, open the Windows Control Panel and select Add / Remove Programs. Select the item listed as "JP Software's 4DOS Registry Extensions (remove only)" and click the Add / Remove button. The registry extensions will be removed without further prompting. The removal operation may not work correctly if you modified the registry entries manually after they were created. JP Software's Take Command/32 also includes a .INF file which creates registry extensions, some of which are the same as those used by 4DOS. Therefore, if you remove the 4DOS extensions you will also remove some extensions used by Take Command/32. If this causes a problem, you can correct it by manually reinstalling the Take Command/32 extensions after removing those for 4DOS. Installing the KSTACK Program in Windows 95 If you want to load KSTACK.COM (required for the KEYSTACK command) it should be loaded separately for each 4DOS session in Windows 95. To do so, include the KSTACK command as the last item on the startup command line when you set up the corresponding shortcut(s). For example, the command line for your shortcut might read: ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 48 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ c:\4dos600\4dos.com c:\4dos600\kstack.com This will load KSTACK when the 4DOS window is opened, then display a prompt. If you install KSTACK in AUTOEXEC.BAT, it may not work properly when multiple 4DOS windows are open, as stacked keystrokes may "bleed through" from one window to another. You can also address this issue by loading KSTACK in your 4START file (see page 34), and using an IF command to make sure it is not loaded from AUTOEXEC.BAT in the primary shell. To do so, use a line like this in 4START: if %_shell ne 0 c:\4dos600\kstack.com Using 4DOS on a Network This section will give you some tips on using 4DOS on a network, and on the proper locations for 4DOS files on a network. For additional details, and any additional information about compatibility with your particular network, see the Compatibility section in the online help. In general, you'll find that you can load and run your network software normally under 4DOS. Network drives will be accessible as normal drives once the network is loaded, and files on the network will be accessible just as if they were on a local hard disk. Some networks support file and directory names beginning with a double backslash [\\], also called "UNC" names, or with a server name followed by a colon, to identify files by their location on the network. 4DOS detects such names and passes them through to the network unaltered, allowing the network software to process them. Some networks support server disk partitions which exceed the standard DOS 2 GB partition size limit. On these drives, 4DOS may not be able to return proper free space or total space figures because the drive size information returned by DOS is not accurate. If you have such a drive you may need to use a network or server utility to obtain accurate partition size and free space information. If you need to boot a diskless workstation from a network drive, see the Novell Netware topic under Software in the Compatibility section of the online help. The techniques described there will allow you to set your system up under ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 49 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ Netware to avoid accesses to the boot drive once 4DOS is running, and can generally be used for other networks as well. 4DOS and Novell Netware 4DOS includes a special 4DOS.INI directive for Netware called NetwareNames. You must set NetwareNames = Yes on systems which load Netware, in order to avoid problems with destroyed environment variables during LOGIN. See the Compatibility topic in the online help for more information. 4DOS can also be set up to run on Novell Netware diskless workstations which boot from the server. To do so, you must make several changes to 4DOS.INI and your other startup files; see the Compatibility section of the online help for complete details. Using 4DOS Under OS/2 4DOS offers almost unlimited flexibility for your OS/2 DOS sessions, and has been specifically designed to take advantage of OS/2 features wherever possible. However, to use DOS, 4DOS, and OS/2 successfully requires some planning if you want to get all the power possible out of each operating environment. This section explains some of the planning you should do and some of the techniques you can use to get everything working together correctly; you can find more advanced information in the Compatibility section of the online help. OS/2 Virtual DOS Machines (VDMs) Under OS/2, you can have multiple desktop objects which start DOS sessions, also called Virtual DOS Machines (VDMs). These may include objects in the Command Prompts window, objects for "migrated applications," objects for DOS and Windows applications, and objects for batch files. Assuming you set up your VDM objects as described in the following section, 4DOS will be loaded as the shell each time a DOS session starts. 4DOS will process 4DOS.INI, execute your 4START file if you have one, and execute AUTOEXEC.BAT. You can start any number of DOS sessions and (within the limits of system resources) have as many running simultaneously as you like. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 50 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ This is fundamentally different from what happens when you boot your computer under DOS or Windows 95. In those environments there is only one 4DOS primary shell, AUTOEXEC.BAT is only executed once each time you boot, and so on. OS/2 gives you much more flexibility, but that flexibility requires planning to get the most out of 4DOS. For example, you can have all your DOS sessions use the same AUTOEXEC.BAT file, or you can have different versions of AUTOEXEC.BAT for different sessions. The same is true of the other startup and exit files (4DOS.INI, 4START, and 4EXIT). Each VDM object contains its own information about how to start DOS and 4DOS for that session. In essence, each object has its own CONFIG.SYS file built into it. The information attached to an object which indicates how to start DOS is called its DOS Properties or DOS Settings. You can modify these settings using the OS/2 Settings or Properties notebook for each object. Use the Program page of the notebook to modify the object's program name, startup directory, and command line parameters. The Session page lets you set the session type. Other pages let you adjust other configuration data for the object. In a new object, each DOS setting starts out with a default value taken from your CONFIG.SYS file. For settings which have no corresponding command in CONFIG.SYS, OS/2 uses a built-in default value. The DOS_SHELL setting, which specifies the command interpreter to use for a DOS session, defaults to the value on the SHELL= line in CONFIG.SYS. The following section explains how to create OS/2 desktop objects for 4DOS. Creating OS/2 Desktop Objects for 4DOS This section assumes you are running OS/2 Warp 4, with the default desktop shell and a standard OS/2 desktop. If you are using an earlier version of OS/2 or a different shell, or have altered your OS/2 desktop configuration substantially, you will need to take those changes into account as you read the instructions below. The 4DOS installation program normally creates a desktop folder which contains an object to start 4DOS from your OS/2 desktop. If you want to create additional objects in other folders, or directly on the desktop, click mouse button 2 on ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 51 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ the installed 4DOS object, select Copy on the popup menu, and copy the object to another location. You can then alter the properties of the new object if you wish. If you need to create a new object for 4DOS, switch to the folder where you want the object to appear and either copy an existing object (use the Copy or Create Another selection on the object's popup menu) or drag a Program Template in from the Templates folder. The new object's Properties notebook should open automatically. Use the Program page of the notebook to modify the program name, parameters, and startup directory. To create a VDM object that gives you a standard 4DOS prompt, place an asterisk [*] in the Program Name field. This tells OS/2 to load the command interpreter and go to a prompt instead of running a specific application. Then go to the Session page and set the session type to DOS Full Screen or DOS Window. While you are on the Settings page, click on the DOS Properties or DOS Settings button. 4DOS will run properly with default DOS properties, but you may want to check that the DOS_SHELL setting is correct, because this determines which command interpreter OS/2 will load when the object is used to start a session. The DOS_SHELL setting should be set as described for the SHELL= line in CONFIG.SYS (see page 38), for example: c:\4dos600\4dos.com c:\4dos600 /p If you've set up CONFIG.SYS for 4DOS as described on page 38, any new VDM objects you create will automatically use the correct DOS_SHELL setting for 4DOS. However, VDM objects which existed before you modified CONFIG.SYS may list COMMAND.COM in the DOS_SHELL setting. You can put command-line switches, a command, or the name of a batch file in the Parameters field (on the Program page of the notebook) for any object. This allows you to run specific commands or set configuration options when you start 4DOS from that object. However, no additional settings are required; the only required item is the asterisk to tell OS/2 to load the default command processor. For details on the command line options available for 4DOS objects see Chapter 4, and the Starting 4DOS section of the online help. If you precede a command name in the Parameters field with /C, 4DOS will exit and return to the OS/2 desktop when the command is finished. This is a "temporary" VDM used to ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 52 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ execute a single command or batch file. Temporary VDMs are also created automatically by OS/2 if you set up an object with the Program Name set to the name of a DOS application. See the Compatibility section of the online help for additional information on using 4DOS under OS/2, including: * More details on using temporary VDMs to run DOS applications and batch files. * Configuring 4DOS for Dual Boot and Boot Manager. * Selecting different startup files (4DOS.INI, AUTOEXEC.BAT, and 4START) for different DOS sessions. * Why changing the DOS_SHELL setting for your DOS session objects may cause difficulty later if you update the SHELL= setting in CONFIG.SYS. Uninstalling 4DOS Manually For automated uninstall instructions, see page 23. The steps required to remove 4DOS from your system manually depend on the operating system you are using: * If you are running 4DOS under Windows 95, and you installed the 4DOS registry extensions, start by removing them as described on page 48. * Next, if you are running 4DOS under Windows 3.x, Windows 95, or OS/2, change or delete any desktop objects that refer directly to 4DOS. Under Windows 95 you can use the Windows Explorer, or manually uninstall the JPSOFT.INF file as described on page 46. * Find the location of COMMAND.COM on your disk (for example, in the root directory, or the DOS directory). Then use your editor to edit the CONFIG.SYS file in the root directory of the boot drive. (If you are running DOS 5 or below, before modifying the CONFIG.SYS file be sure you have a bootable floppy disk as described on page 36). Look for the line which begins with SHELL=, and either delete it, or insert the characters "REM " at the beginning of the line. This converts the line ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 53 Chapter 5 / 4DOS Configuration and Notes ------------------------------------------------------------------ into a "remark" or comment. Next, add a new line like this: SHELL=d:\path\COMMAND.COM d:\path /P where "d:\path" is the drive and directory for COMMAND.COM (this same directory name is repeated after the full name of COMMAND.COM and before the /P). If you were previously running COMMAND.COM with a /E:nnnn switch to set the size of your environment, add it to this line as well. * After CONFIG.SYS has been modified, edit your AUTOEXEC.BAT file to remove any changes made to accommodate 4DOS. Look for a command beginning SET COMSPEC= and another which loads the 4DOS file KSTACK.COM. The SET COMSPEC command will not be present on most systems. If it's there, remove it, or change it to read: SET COMSPEC=d:\path\COMMAND.COM where "d:\path" is replaced by the correct drive and directory for COMMAND.COM. Then add "REM " in front of the KSTACK.COM command to convert it to a comment, or delete the line entirely. Now reboot your system, and you should be back up and running under COMMAND.COM. You can check the 4DOS directory for any files you placed there that you want to save. Then delete the 4DOS files and remove the 4DOS directory if you wish to do so. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 54 Chapter 6 / 4OS2 Configuration and Notes ------------------------------------------------------------------ Chapter 6 / 4OS2 Configuration and Notes 4OS2 works well with virtually all computers that run OS/2 version 2.1 or later. This chapter provides the basic information you need to run 4OS2 in any of the standard PC environments. If you need more detailed technical information or troubleshooting assistance on any of these topics, consult the Troubleshooting, Service, and Support topic in the 4OS2 online help. If you used the automated installation program to install 4OS2, you can safely skip this chapter, and return to it only if you have difficulty with the program or want to fine-tune it meet your needs. 4OS2 Installation Notes You can install and use 4OS2 under OS/2 version 2.1 or above, including OS/2 Warp 3 and 4. When you install 4OS2, your OS/2 CONFIG.SYS file must be modified to make 4OS2 the default OS/2 command processor, and to update certain directives to include the path to your 4OS2 files. You can allow the installation software to make these changes automatically, or you can make them yourself at a later time (see Manual Installation of 4OS2 below for details). Manual Installation of 4OS2 This section is for advanced users, and assumes you are generally familiar with CONFIG.SYS and other concepts such as ASCII editors and batch files. In most cases you can select the installation options you need using the automated installation program, and manual installation is not necessary. In order to install 4OS2 manually, you must extract or copy the necessary files, brand 4OS2 if necessary, create or modify any configuration files you need, and then create the necessary commands to start the program on your system. Extracting or Copying the Program Files When you extract or copy the 4OS2 files, be sure to place them in their own directory, rather than using the same ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 55 Chapter 6 / 4OS2 Configuration and Notes ------------------------------------------------------------------ directory as a previous version of the program, a directory used by other JP Software products, or a directory used by other software. We strongly recommend that you place all of the 4OS2 files in the same directory. See 4OS2 Files and Directories on page 58 for some important considerations if you choose not to follow this recommendation. The method used to extract or copy the files depends on how you obtained your copy of the program: * If you have a JP Software diskette you must use the installation program described in the preceding section because the files are compressed on the distribution disk. You cannot simply copy the files onto your hard disk. Select Custom Install and follow the prompts to specify the installation directory and copy the files. Then exit the installation program with Ctrl-X, or answer No when prompted for whether to proceed with each additional step. * If you have a copy purchased electronically you must use the installation program to extract the files as described above. First extract the installation files from the compressed file you downloaded into a temporary directory, then run the INSTALL program. Use the Custom Install option as described in the preceding paragraph. * If you have the JP CD Suite, all of the files are stored uncompressed on the CD, in the \4OS2 directory, and you can copy them manually if you wish. However, we still recommend that you use the installation program described above to copy the files. Some files may be renamed after copying, and some files are used only during the installation process and do not need to be copied to your hard disk. If you copy the files manually, a few may not have the correct names, and you may copy more files than you need, resulting in wasted hard disk space. * If you have a downloaded trial copy of the program, or a copy distributed on a CD or diskette of trial software, extract the files into a new directory using the appropriate decompression program (e.g. PKUNZIP or OS/2 UNZIP). ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 56 Chapter 6 / 4OS2 Configuration and Notes ------------------------------------------------------------------ "Branding" 4OS2 (If you are not familiar with branding, refer to the general information on page 21 before continuing with this section.) If you have purchased a copy of 4OS2, the automated installation procedure will normally run the BR4OS2 program to check your name, serial number, and validation code and "brand" 4OS2 as a registered product (in some cases 4OS2 may not operate properly until this step is completed). If you need to brand 4OS2 manually, start a 4OS2 or CMD.EXE session, change to the directory where 4OS2 is stored, and enter the command: [c:\4os2300] br4os2 Follow the instructions displayed by BR4OS2 to enter your name, serial number, and validation code. All information must be entered exactly as shown on your original brand card, label, or electronically delivered branding information; you cannot change spelling, capitalization, or punctuation. If you are upgrading from a previous version and using an old copy of the BRAND.EXE program distributed with that version, you must start BRAND from a 4DOS, CMD.EXE, or COMMAND.COM session, not from 4OS2, because older versions of BRAND cannot brand 4OS2 while it is running. (The newer BR4OS2 program does not have this restriction.) Updating CONFIG.SYS When you're ready to finish installing 4OS2, you need to make five changes to your CONFIG.SYS file. Use an ASCII editor to make these changes. The examples below assume that 4OS2 is installed in the C:\4OS2300 directory; if you use a different directory, alter the instructions accordingly. * Find the line in CONFIG.SYS that begins with the words SET OS2_SHELL. It should look something like this: SET OS2_SHELL=C:\OS2\CMD.EXE Change the line to point to 4OS2.EXE, instead of CMD.EXE. The altered line should look something like this: SET OS2_SHELL=C:\4OS2300\4OS2.EXE ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 57 Chapter 6 / 4OS2 Configuration and Notes ------------------------------------------------------------------ * Find the line that begins with the words SET COMSPEC. It should look something like this: SET COMSPEC=C:\OS2\CMD.EXE Change this line so that it also points to 4OS2.EXE: SET COMSPEC=C:\4OS2300\4OS2.EXE * Find the three lines that begin with SET BOOKSHELF, SET DPATH, and LIBPATH (these lines may not all be together in CONFIG.SYS). Each is a list of directories separated by semicolons, for example: SET BOOKSHELF=C:\OS2\BOOK;... SET DPATH=C:\OS2;... LIBPATH=C:\OS2\DLL;... Add a semi-colon [;] and the name of the 4OS2 directory to the end of each line: SET BOOKSHELF=C:\OS2\BOOK;...;C:\4OS2300 SET DPATH=C:\OS2;... ;C:\4OS2300 LIBPATH=C:\OS2\DLL;... ;C:\4OS2300 Check the changes you have made and save the CONFIG.SYS file. Then exit from your editor, shut down OS/2, and reboot your system. You should be up and running under 4OS2 when you start a full-screen or windowed OS/2 command-line session. 4OS2 Files and Directories We strongly recommend that you place all 4OS2 files in the same directory. If you do not do so, you will probably have to explicitly set the locations of 4OS2 files to avoid problems. If you do wish to move files to different directories, the following information will help you set up the programs correctly: 4OS2.EXE is the 4OS2 program file. It must be in the directory specified in the SET OS2_SHELL and SET COMSPEC lines in your CONFIG.SYS file as explained above. JPOS2DLL.DLL is a library used by 4OS2.EXE (and by Take Command for OS/2). This file must be in a directory listed in the LIBPATH setting in CONFIG.SYS. If you ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 58 Chapter 6 / 4OS2 Configuration and Notes ------------------------------------------------------------------ prefer, you can move this file into the standard OS/2 DLL directory, \OS2\DLL. 4OS2.INF contains the text for the 4OS2 help system. For the help system to work properly, the directory containing this file must be included in the BOOKSHELF environment variable, which is usually set with a SET BOOKSHELF command in CONFIG.SYS. If you prefer, you can move this file into the standard OS/2 bookshelf directory, \OS2\BOOK. 4OS2H.MSG contains the help text for the /? option that is available as part of each 4OS2 internal command. For this feature to work properly, the directory containing this file must be included in the DPATH environment variable, which is usually set with a SET DPATH command in CONFIG.SYS. If you prefer, you can move this file into the standard OS/2 directory for such files, \OS2\SYSTEM. KEYSTACK.EXE is a utility used by the KEYSTACK command to pass keystrokes to other applications. For the KEYSTACK command to work, this file must be in the same directory as 4OS2.EXE, or in a directory included in your PATH. OPTION2.EXE is a utility used by the OPTION command to configure 4OS2. For the OPTION command to work, this file must be in the same directory as 4OS2.EXE, or in a directory included in your PATH. SHRALIAS.EXE is a utility used by the SHRALIAS command to save the shared alias and history lists between 4OS2 sessions. For the SHRALIAS command to work, this file must be in the same directory as 4OS2.EXE, or in a directory included in your PATH. Creating Desktop Objects for 4OS2 This section assumes you are running OS/2 Warp 4, with the default desktop shell and a standard OS/2 desktop. If you are using an earlier version of OS/2 or a different shell, or have altered your OS/2 desktop configuration substantially, you will need to take those changes into account as you read the instructions below. The 4OS2 installation program normally creates a desktop folder which contains objects to start 4OS2 and its online help. If you want to create additional objects in other ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 59 Chapter 6 / 4OS2 Configuration and Notes ------------------------------------------------------------------ folders, or directly on the desktop, click mouse button 2 on the installed 4OS2 object, select Copy on the popup menu, and copy the object to another location as desired. You can then alter the properties of the new object if you wish. If you need to create a new 4OS2 object, switch to the folder where you want the object to appear and either copy an existing object (use the Copy or Create Another selection on the object's popup menu) or drag a Program Template in from the Templates folder. The new object's Properties notebook should open automatically. Use the Program page of the notebook to modify the path and file name, parameters, and startup directory. You must also set the session type on the Session page of the notebook whenever the Path and File Name field is changed on the Program page. If you allowed the installation program to modify CONFIG.SYS, or made the appropriate changes manually so that 4OS2 is the default command interpreter named on the SET OS2_SHELL line, you can use an asterisk [*] in the Path and File Name field and the new object will start 4OS2 as the default command processor. If you did not modify CONFIG.SYS for 4OS2, you must put the full path and filename for 4OS2.EXE in the Path and File Name field. You can put command-line switches, a command, or the name of a batch file in the Parameters field for any object. This allows you to run specific commands or set configuration options when you start 4OS2 from that object. However, no additional settings are required; the only required item is the drive and path for 4OS2.EXE (or an asterisk if 4OS2 is installed as your default command processor). For details on the command line options available for 4OS2 objects see Chapter 4, and the Starting 4OS2 section of the online help. For more information on creating and configuring desktop objects see your OS/2 documentation. The 4OS2 Help System The 4OS2 help text, in the file 4OS2.INF, covers 4OS2 features and internal commands. OS/2 ships with reference text for CMD.EXE internal and OS/2 external commands, in the file \OS2\BOOK\CMDREF.INF. This text is normally displayed along with 4OS2's help when the HELP command or F1 key is used, to assist you in obtaining help on external OS/2 commands like CHKDSK and FORMAT. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 60 Chapter 6 / 4OS2 Configuration and Notes ------------------------------------------------------------------ To accomplish this, 4OS2 passes the help file name "4OS2+CMDREF" to the OS/2 help program, so that the help program opens both help "books". You can specify a different set of "books" to be opened when HELP or F1 is invoked by adjusting the HelpBook directive in 4OS2.INI, or the corresponding entry on the Options 2 page in the configuration notebook. For example, to set up 4OS2 so that only 4OS2 help is displayed (without the CMDREF book) when F1 is pressed, you would include the following directive in 4OS2.INI, or make the corresponding change in the configuration notebook: HelpBook=4OS2 When more than one book is listed in the HelpBook setting, the OS/2 help program will see the combined group as a single book. The displayed Table of Contents will include the tables of contents from all the listed books, joined together as one group of topics with no divisions to show where one book ends and the next begins. If any of the listed books are not available the help program will not start. If you start the help system from a windowed 4OS2 session, you will be returned to that session when you are done. If you start the help system from a full-screen session, you must manually return to that session using standard OS/2 methods for switching between sessions (this is due to the design of the OS/2 help system and is not a limitation of 4OS2). You can also keep the help window on the screen and return to the 4OS2 session, switching between the two sessions as needed. This may be useful when you are writing a batch file, working on a complex command, or experimenting with 4OS2. The 4OS2 installation program sets up a separate object for the help system so that you can load the help file directly. To create a similar object manually, use entries like this on the Program page of the object's Settings notebook: Path and File Name: VIEW.EXE Parameters: 4OS2 Working Directory: d:\path where "d:\path" is the directory where you installed 4OS2. The help system can also be used to obtain help on OS/2 error codes. If you type either of these commands: ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 61 Chapter 6 / 4OS2 Configuration and Notes ------------------------------------------------------------------ [c:\] help nnnn [c:\] help sysnnnn where "nnnn" is an OS/2 system error number, HELP will display an explanation of the OS/2 error. This feature works by running the OS/2 program HELPMSG.EXE which opens the file OSO001.H to get the explanation. For this feature to work, HELPMSG.EXE must be in a directory that is in your PATH, and the data file OSO001H.MSG must be in a directory in your DPATH (OS/2 sets up HELPMSG.EXE and OS0001H.MSG this way by default). You can also use the 4OS2 HELP command to change the PROMPT setting. HELP ON will change the default prompt to $i[$p], and HELP OFF will change the default prompt to [$p]. This feature is included for compatibility with OS/2's CMD.EXE, and is implemented by running the HELP.CMD file which comes with OS/2 (typically stored in the \OS2 directory). Changing the prompt is probably better accomplished by using the PROMPT command instead of HELP ON or HELP OFF. 4OS2 also supports the /? switch to display help for any command. Using /? will display brief help text for the command within the 4OS2 window. Using STARTUP.CMD If you have a STARTUP.CMD file in the root directory of your OS/2 boot drive, OS/2 will automatically create a windowed 4OS2 session when the system boots and will tell that session to execute STARTUP.CMD. (This is a feature of OS/2 and does not depend on 4OS2. If CMD.EXE is your OS/2 command interpreter, it will be used to run STARTUP.CMD.) You can use STARTUP.CMD to start other sessions, to set up a global alias list, to execute the SHRALIAS command, etc., just as you might use AUTOEXEC.BAT under DOS. STARTUP.CMD will be executed once, when your system boots, not every time a 4OS2 session is started. If you place the command EXIT at the end of STARTUP.CMD, the session created to run STARTUP.CMD will end when that command is executed, and any global alias and history lists will be discarded (unless another 4OS2 session has been started or SHRALIAS has been executed). If you don't include an EXIT, the session will remain open and can be used as a normal windowed 4OS2 session. If you have a 4START file, it will be run before STARTUP.CMD. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 62 Chapter 6 / 4OS2 Configuration and Notes ------------------------------------------------------------------ Uninstalling 4OS2 Manually For automated uninstall instructions, see page 23. To manually remove 4OS2 from your system, follow these steps: * First, find the location of CMD.EXE on your disk (for example, in the \OS2 directory). * Delete or change any desktop objects that refer directly to 4OS2. If you want to continue using the same objects to run programs or batch files with CMD.EXE, substitute the full path to CMD.EXE for the reference to 4OS2. Change any startup parameters as necessary. * Use an ASCII editor to edit your CONFIG.SYS file. Look for a line that starts SET OS2_SHELL, and another that starts SET COMSPEC: SET OS2_SHELL=C:\4OS2300\4OS2.EXE SET COMSPEC=C:\4OS2300\4OS2.EXE Change both lines to point to CMD.EXE, for example: SET OS2_SHELL=C:\OS2\CMD.EXE SET COMPSEC=C:\OS2\CMD.EXE * Search the CONFIG.SYS file for any other mention of the 4OS2 directory. In a typical installation, the directory name will be listed in the SET BOOKSHELF, SET DPATH, and LIBPATH lines. You may also have added it to the SET PATH line (although the installation program does not do so). Remove each reference to the 4OS2 directory, but leave the rest of each line unchanged. * Finally, if you have a STARTUP.CMD file in the root directory of the boot drive, load it into your editor and remove any references in it to 4OS2 and any commands that depend on 4OS2 (such as commands that load aliases). Now reboot your system, and you should be back up and running under CMD.EXE when you start a full-screen or windowed command-line session. Check your 4OS2 directory for any files you placed there that you want to save. Then you can then delete the 4OS2 files and remove the 4OS2 directory if you wish to do so. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 63 Chapter 7 / 4NT Configuration and Notes ------------------------------------------------------------------ Chapter 7 / 4NT Configuration and Notes 4NT works well with virtually all Intel-based computers that run Windows NT version 3.5 or later (contact JP Software for information on running 4NT on non-Intel platforms). This chapter provides the basic information you need to run 4NT. If you need more detailed technical information or troubleshooting assistance on any of these topics, consult the Troubleshooting, Service, and Support topic in the 4NT online help. If you used the automated installation program to install 4NT, you can safely skip this chapter, and return to it only if you have difficulty with the program or want to fine-tune it meet your needs. 4NT Installation Notes When you install 4NT under Windows NT 3.5 or 3.51, no system files will be modified. If you install 4NT under Windows NT 4.x the installation program will create a Start menu group for JP Software products, including 4NT. In addition, a small group of entries will be added to the system registry (if you allow such modifications); for more details see page 67. Installing 4NT does not modify, remove, or otherwise alter any of your other system files. If you regularly run 16-bit character-mode applications which "shell to DOS" (i.e., start a secondary command prompt session), including 16-bit MAKE utilities, we recommend that you enable the NTCMDPROMPT directive in the \WINNT\SYSTEM32\CONFIG.NT file. This is a Windows NT feature which affects operation of shells started from 16-bit programs, and is not specifically related to 4NT. However, in our experience using it improves operation, and prevents certain problems with secondary shells (e.g., requiring you to type an extra EXIT command to return to the parent application). NTCMDPROMPT may or may not work well in your particular situation, and experimentation is usually required to determine the best configuration. For further documentation on NTCMDPROMPT read the comments provided by Microsoft in CONFIG.NT. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 64 Chapter 7 / 4NT Configuration and Notes ------------------------------------------------------------------ Manual Installation of 4NT This section is for advanced users and assumes you are generally familiar with ASCII editors, batch files, and other similar concepts. In most cases you can select the installation options you need using the automated installation program, and manual installation is not necessary. In order to install 4NT manually, you must extract or copy the necessary files, brand 4NT if necessary, and then create desktop objects to start the program on your system. Extracting or Copying the Program Files When you extract or copy the 4NT files, be sure to place them in their own directory, rather than using the same directory as a previous version of the program, a directory used by other JP Software products, or a directory used by other software. We strongly recommend that you place all of the 4NT files in the same directory. See 4NT Files and Directories on page 68 for some important considerations if you choose not to follow this recommendation. The method used to extract or copy the files depends on how you obtained your copy of the program: * If you have a JP Software diskette you must use the installation program described in Chapter 2 because the files are compressed on the distribution disk. You cannot simply copy the files onto your hard disk. Select Custom Install and follow the prompts to specify the installation directory and copy the files. Then exit the installation program with Ctrl- X, or answer No when prompted for whether to proceed with each additional step. * If you have a copy purchased electronically you must use the installation program to extract the files as described above. First extract the installation files from the compressed file you downloaded into a temporary directory, then run the INSTALL program. Use the Custom Install option as described in the preceding paragraph. * If you have the JP CD Suite, all of the files are stored uncompressed on the CD, in the \4NT directory, ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 65 Chapter 7 / 4NT Configuration and Notes ------------------------------------------------------------------ and you can copy them manually if you wish. However, we still recommend that you use the installation program described above to copy the files. Some files may be renamed after copying, and some files are used only during the installation process and do not need to be copied to your hard disk. If you copy the files manually, a few may not have the correct names, and you may copy more files than you need, resulting in wasted hard disk space. * If you have a downloaded trial copy of the program, or a copy distributed on a CD or diskette of trial software, extract the files into a new directory using the appropriate decompression program (e.g. PKUNZIP). "Branding" 4NT (If you are not familiar with branding, refer to the general information on page 21 before continuing with this section.) If you have purchased a copy of 4NT, the automated installation procedure will normally run the BR4NT program to check your name, serial number, and validation code and "brand" 4NT as a registered product (in some cases 4NT may not operate properly until this step is completed). If you need to brand 4NT manually, start a 4NT or CMD.EXE ("MS-DOS Prompt") session, change to the directory where 4NT is stored, and enter the command: [c:\4nt300] br4nt Follow the instructions displayed by BR4NT to enter your name, serial number, and validation code. All information must be entered exactly as shown on your original brand card, label, or electronically delivered branding information; you cannot change spelling, capitalization, or punctuation. If you are upgrading from a previous version and using an old copy of the BRAND.EXE program distributed with that version, you must start BRAND from a CMD.EXE session, not from 4NT, because older versions of BRAND cannot brand 4NT while it is running. (The newer BR4NT program does not have this restriction.) ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 66 Chapter 7 / 4NT Configuration and Notes ------------------------------------------------------------------ Updating System Files and the Registry for 4NT 4NT doesn't require any changes to any system files. Once you have placed the 4NT program files in their own directory, the installation is finished except for creating desktop objects to start the program (see page 68 below). JP Software distributes a file of registry extensions for 4NT, for use under Windows NT 4.x. The registry extensions are stored in the file JP4NT.INF. Installing these extensions will: * Designate 4NT .BTM files (enhanced batch files) as batch files. They will then be recognized as such by the Windows Explorer; * Provide an additional "open" option in the context (mouse button 2) menu of all batch files, to explicitly run the file with 4NT; and * Create a new entry in the context menu of drives and directories to launch 4NT in that drive / directory. You will have the option to install JP4NT.INF automatically during the 4NT installation process. You can also install it manually by opening the 4NT directory from within the Windows Explorer, clicking on JP4NT.INF with mouse button 2, and selecting INSTALL from the popup menu. If you have a downloaded trial copy of 4NT, JP4NT.INF will not be installed automatically; you must use manual installation. See the comments in the file for additional details. JP4NT.INF assumes that you have a relatively standard system configuration. If you have modified basic items in your registry (such as the characteristics of the system file type "batfile"), the registry extensions may not work correctly. To adjust the registry entries made when you install JP4NT.INF, open the Windows Explorer, and select Options on the View menu. Click on the File Types tab and find the listing for batch files (typically under "MS-DOS Batch File"). Use the Edit button to adjust this listing. JP4NT.INF also makes minor changes to the Drive and Directory types; you may want to modify these as well. Note that some of these file types may not be editable on your system, depending on the settings of various edit flags in the registry. To remove the registry entries created by JP4NT.INF, open the Windows Control Panel and select Add / Remove Programs. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 67 Chapter 7 / 4NT Configuration and Notes ------------------------------------------------------------------ Select the item listed as "JP Software's 4NT Registry Extensions (remove only)" and click the Add / Remove button. The registry extensions will be removed without further prompting. The removal operation may not work correctly if you modified the registry entries manually after they were created. JP Software's Take Command/32 also includes a .INF file which creates registry extensions, some of which are the same as those used by 4NT. Therefore, if you remove the 4NT extensions you will also remove some extensions used by Take Command/32. If this causes a problem you can correct it by manually reinstalling the Take Command/32 extensions after removing those for 4NT. 4NT Files and Directories We strongly recommend that you place all 4NT files in the same directory. If you do not do so, you will probably have to explicitly set the locations of 4NT files to avoid problems. If you do wish to move files to different directories, the following information will help you set up the programs correctly: 4NT.EXE is the 4NT program file. It must be in the directory specified in the Command Line field of every 4NT object. 4NT.HLP contains the text for the 4NT help system. 4NT.HLP must be in the same directory as 4NT.EXE. SHRALIAS.EXE is a small utility that is used by the SHRALIAS command to save the shared alias and history lists between 4NT sessions. For the SHRALIAS command to work, this file must be in the same directory as 4NT.EXE, or in a directory included in your PATH. Creating Desktop Objects for 4NT The method you use to create a desktop object for 4NT depends on whether you are using Explorer or Program Manager as your shell. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 68 Chapter 7 / 4NT Configuration and Notes ------------------------------------------------------------------ Creating Explorer Shortcuts This section assumes you are running Windows NT 4.x, with Explorer as your Windows shell, and with a standard Windows desktop. If you are using Program Manager, see the next section. If you have altered your Windows desktop configuration substantially, you may need to take those changes into account as you read the instructions below. When 4NT is installed it normally creates a JP Software program group which appears on the Start Menu under Programs, and includes items to start 4NT and its online help. The installation program also creates a desktop shortcut for 4NT. These entries are created based on the file JPSOFT.INF, which is distributed with Take Command. If you have a downloaded trial copy of 4NT, JPSOFT.INF will not be installed automatically; if you want to install it you must do so manually. See the comments below and in the file for additional details. If you need to create a similar program group or shortcuts manually _ for example, if the JP Software group on the Start menu is inadvertently damaged or deleted _ you can use the Windows Explorer's facilities for creating shortcuts and modifying the desktop and / or the Start menu (see below). You can also install JPSOFT.INF manually if you wish; see the comments in the file for details. JPSOFT.INF is designed to install JP Software's 4DOS, 4NT, and Take Command/32 products under Windows 95 and Windows NT. It will install the product stored in the directory from which JPSOFT.INF is run; the entries for other products and operating systems will be ignored. To remove the desktop shortcuts and group created by JPSOFT.INF, open the Windows Control Panel and select Add / Remove Programs. Select the item listed as "JP Software program shortcuts (remove shortcuts and group)" and click the Add / Remove button. The JP Software group and all of its entries will be removed without further prompting. (To remove only the entries for a single product, use the Windows Explorer.) The removal operation may not work correctly if you modified the group or shortcuts manually after they were created. If you want to create additional shortcuts elsewhere on the Start menu, or modify the Programs entries, click mouse button 2 in an open area of the Task Bar, and select ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 69 Chapter 7 / 4NT Configuration and Notes ------------------------------------------------------------------ Properties on the popup menu. Select the Start Menu Programs tab and modify or adjust the menus as required. You can also manually create one or more shortcuts on the desktop to run 4NT. To do so click with mouse button 2 in any open area of the desktop. On the popup menu click New, then Shortcut. Fill in the drive and path as d:\path\4NT.EXE (use the appropriate drive and path for your system). Add any other command line options you wish to set to the end of the line. You can also put command-line switches, a command, or the name of a batch file at the end of the command line for any shortcut. This allows you to run specific commands or set configuration options when you start 4NT from that shortcut. For details on the command line options available, see Chapter 4 and the Starting 4NT section of the online help. For more information on creating and configuring shortcuts or modifying the Start Menu, see your Windows 95 or Windows NT documentation. Creating Program Manager Items This section applies to Windows NT 3.5 or 3.51 with Program Manager as the shell. When 4NT is installed it normally creates a program group which appears in the Program Manager, and includes items to run 4NT and its online help. If you want to create a new item for 4NT in any group, use the Program Manager's File / New menu selection. Set the command line to d:\path\4NT.EXE (use the appropriate drive and path for your system). You can put command-line switches, a command, or the name of a batch file at the end of the command line for any item. This allows you to run specific commands or set configuration options when you start 4NT from that item. The 4NT Help System When you start the 4NT help system, 4NT opens a new window to run the standard Windows NT help program. The help program displays the help text from the file 4NT.HLP, and lets you browse through it. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 70 Chapter 7 / 4NT Configuration and Notes ------------------------------------------------------------------ 4NT's help text does not cover the Windows NT external commands because they are included in Windows NT's built-in Command Reference. If you start the help system from a 4NT window on the Windows NT desktop, you will be returned to that window when you close the help program. However, if you have switched the window to full-screen mode before invoking the help system, you must return to 4NT manually (using standard Windows NT methods for switching between windows). This is due to the design of Windows NT Help and is not a limitation of 4NT. You can also keep the help window on the screen and return to the 4NT window, switching between the two windows as needed. This may be useful when you are writing a batch file, working on a complex command, or experimenting with 4NT. In order for the 4NT help system to work properly, the help text file, 4NT.HLP, must be in the same directory as 4NT.EXE. The 4NT installation program sets up a separate object for the help system so that you can load the help file directly. To create a similar object manually, create an object with a command line like this: Command Line: WINHELP C:\4NT300\4NT.HLP (Change the drive and path to reflect the location of 4NT.HLP on your system.) 4NT also supports the /? switch to display help for any command. Using /? will display help for the command using the Windows NT help system. Uninstalling 4NT Manually For automated uninstall instructions, see page 23. The steps required to remove 4NT manually depend on the version of Windows NT you are using: * If you installed the 4NT registry extensions, start by removing them as described on page 67. * Next, use the Windows Explorer or Program Manager to remove any shortcuts or desktop objects for 4NT, or manually uninstall the JPSOFT.INF file as described on page 69. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 71 Chapter 7 / 4NT Configuration and Notes ------------------------------------------------------------------ * Check the 4NT directory for any files you placed there that you want to save. Then you can then delete the 4NT files and directory from your hard drive. ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 72 Index ------------------------------------------------------------------ Index 4OS2 (continued) installation directory, 55, 58 4 manual, 55 notes, 55 4DOS uninstalling, 63 branding, 37 4OS2.INF, 59, 60 compatibility with 4OS2.INI, see .INI file memory, 42 4START, 34 Microsoft Windows, see and startup command, 33 Microsoft Windows single-step option, 33 Microsoft Windows 95, see Microsoft Windows 95 A older DOS versions, 36 operating system Alias list, local and global, versions, 35 42 OS/2, see OS/2 Aliases, 14 video display, 42 local and global, 31 configuration, 35 technical support for, 5 installation ANSI driver, and 4DOS, 42 directory, 36, 40 APPEND command, and 4DOS, 43 manual, 36 AUTOEXEC.BAT notes, 35 and installation, 21, 39 uninstalling, 53 and startup command, 33 4DOS.HLP, 40, 41 disabling, 30 4DOS.INI, see .INI file modifying, for 4DOS, 35 4DOS.PIF, 45 running, 32 4EXIT, 34 single-step option, 33 4HELP.EXE, 40, 41 starting KSTACK.COM, 39 4NT and operating system versions, 64 B branding, 66 configuration, 64 Batch files, 15 installation startup, see Startup directory, 65, 68 options manual, 65 technical support for, 5 notes, 64 under Windows 95, 47 uninstalling, 71 under Windows NT, 67 4NT.HLP, 68, 70 BOOKSHELF setting, for 4OS2, 4NT.INI, see .INI file 58, 63 4OS2 Branding, 21 and operating system 4DOS, 37 versions, 55 4NT, 66 branding, 57 4OS2, 57 configuration, 55 upgrades, 22, 23 creating desktop objects .BTM files, see Batch files for, 59 folder, 59 ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 73 Index ------------------------------------------------------------------ C Configuration (continued) 4OS2, 55 CMD.EXE (OS/2), help for, 60 4START and 4EXIT, 34 Colors OPTION command, 34 problems with, in 4DOS, 42 primary and secondary setting, in 4NT, 32 shells, 28 Command history, local and startup options, 29 global, 31 Contacting JP Software, 3 Command line enhancements, 12 Critical errors, 31 Command line options, see Customer service, 3 Startup options COMMAND.COM, in Microsoft Windows, 44 D Commands new and enhanced, 9 DBLSPACE, and 4DOS, 43 startup, see Startup Directory history list, local options and global, 31 Compatibility (4DOS) Diskless workstations, 49 and DOS, 43 Disks and Microsoft Windows, 44 drives, and 4DOS, 42 and Microsoft Windows 95, free space, and 4DOS, 43 45 DOS and networks, 49 older versions, and 4DOS, and Novell Netware, 50 36 COMSPEC shell, 9 environment variable versions of, 1 setting automatically, DPATH setting, for 4OS2, 58, 29 63 setting manually, 39 DR DOS, and 4DOS, 1, 43 in OS/2, 57, 63 DRVSPACE, and 4DOS, 43 path, 29, 38 CONFIG.NT, 64 CONFIG.SYS E and installation, 21, 38 DOS Enhancements configuration aliases and batch files, utilities, 43 14 modifying, for 4DOS, command line, 12 35 commands, 9 OS/2 configuration, 14 changes for 4OS2, 57, Environment, memory for, 31 63 modifying, for 4DOS, 38 F modifying, for 4OS2, 55 FASTOPEN, and 4DOS, 44 Configuration, 14, 28 File locations, see .INI file, 34 Installation directory 4DOS, 35 4NT, 64 ------------------------------------------------------------------ Copr. 1997 JP Software Inc. 4DOS, 4OS2, 4NT Install Guide / 74 Index ------------------------------------------------------------------ File names, on networks, and Installation (continued) 4DOS, 49 preparing for, 18 FORMAT /S command, and 4DOS, of upgrades, 19 43 reversing, 23 4DOS, 53 4NT, 71 H 4OS2, 63 InstallPath, 39 Hard drives, and 4DOS, 42 Internet HELP command, MS-DOS, 43 JP Software addresses on, Help system, 3, 25 4 /?
