PERUSE by 

PURPOSE:

         PERUSE is a TSR that captures and saves screen information as
it scrolls off the top of the screen. Once loaded, pressing the ScrollLock
key will put you into redisplay mode. You can then use the cursor keys to
browse through scrolled screen data.

SYNTAX:

The syntax for loading PERUSE into memory is:

                               PERUSE /Xn | /En

where n is the size of the the scroll buffer in kilobytes, and must be in the range 16 to 8192.

         The /X parameter tells PERUSE to create the scroll buffer in
extended memory; the /E parameter tells PERUSE to create the buffer in
expanded memory. An extended or expanded memory driver must be loaded
in order to use PERUSE.

         To remove PERUSE from memory, type:

                               PERUSE /U

If any memory resident programs have been loaded after PERUSE, the program will be unable to unload and will display an error message.

REMARKS:

         PERUSE is similar in functionality to a utility published in
PC Magazine back in 1985: WaitaSec. But because of its age, WaitaSec
works only with EGA video adapters. PERUSE works with VGA as well, and
stores the screen buffer in extended or expanded memory to minimize
conventional memory usage.

         Like WaitaSec, PERUSE uses the ScrollLock key to turn redisplay
mode on and off. When in redisplay mode, you can use the following cursor
keys to move through the scroll buffer and view scrolled information: Up
and Down arrows, PageUp, PageDown, Home, and End. Pressing the F1 key
while in redisplay mode will bring up a help screen listing the cursor
keys you can use.
