EXAMPLE BATCH FILE COMMANDS FOR USE WITH /Z switch:

    @ECHO OFF

    @SET IFF=C:\UTILS\PKUNZIP.EXE        ;set IFF= environment variable

    @IFF %1.ZIP/AZ%2         ; use %1 parameter as first 8 characters
                             ; in .ZIP file name.  Specify /AZ,
                             ; use %2 parameter as addtional switches.
    @SET IFF=                ; remove IFF= environment variable

                             ; beep if file not found

    @IF ERRORLEVEL == 1 ECHO .ZIP file not found!

    The above batch file command sequence sets the IFF environment variable
to path and file name of pkunzip.exe, removes the IFF environment
variable to restore environment space, checks IFF DOS errorlevel exit code
for file not found.
