          PURPOSE:

          What Extension is  a small utility designed  to be used in  batch
          files.  It will check the  filename provided to it on the command
          line and  return an  errorlevel based on  the extension.   It  is
          primarily  designed to  check for  compressed files;  however, it
          will  test for any extension provided  the extension is specified
          on the command line.


          FORMAT:

               WHATEXT [/? or /V] <filename> [ext1] [ext2] ... [extn]

               /?          =  show help screen
               /V          =  show version information
               <filename>  =  filename to test, may include path
               [ext]       =  optional additional extensions to test for
                              will return errorlevels beginning at 10

               Errorlevels:
                       -2  =  no filename sent to program
                       -1  =  filename has no extension
                        0  =  unknown extension
                        1  =  ZIP
                        2  =  LZH
                        3  =  ARC
                        4  =  PAK
                        5  =  ZOO
                        6  =  ARJ
                       10  =  first optional extension on command line
                        n  =  9 + nth extension on command line

          EXAMPLES:

            WHATEXT D:\DOWNLOADS\NEWFILE.ZIP    ->    Errorlevel = 1

            WHATEXT D:\NEW\SOMEFILE             ->    Errorlevel = -1

            WHATEXT THISFILE.EXE                ->    Errorlevel = 0


          To test for additional  extensions, add them to the  command line
          after  the filename. If the  filename contains one  of these, the
          errorlevel returned will be  9 + the extension's position  on the
          command line with the first extension being in position one.







          For instance, if you enter

            WHATEXT myfile.com TXT COM GIF

          WHATEXT will return an errorlevel of 11 ( TXT = 10, COM = 11, GIF
          = 12 ).
