QEXIST.EXE is a program that will act similar to the COMMAND.COM
command IF EXIST. There is one major difference though and that is
QEXIST will return an ERRORLEVEL to your BAT or CMD file with different
error codes for different errors. These error codes are the DOS and OS/2
error codes so they have the same meaning. QEXIST also traps hard errors
such as DRIVE NOT READY and SECTOR NOT FOUND, this will allow you to
trap those nasty abort, retry, ignore messages or for those of you
running under OS/2, those irritating popup dialog boxes. I have
included two command files (one for DOS and the other for OS/2)
although they are virtually the same. These files will give you an
example of how QEXIST works.
An Example of Using QEXIST:
ECHO *** INSERT INSTALL DISK IN DRIVE A: ***
IF ERRORLEVEL 21 GOTO NODISK
IF ERRORLEVEL 2 GOTO NOTFOUN
QEXIST.EXE was written in "C" and is a bound executable. This means it
will run under OS/2 and DOS.

your heart desires, but you must not alter the program in any way
and you must distribute this documentaion file unaltered.
