- 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: ***
- QEXIST A:INSTALL.DAT
- IF ERRORLEVEL 21 GOTO NODISK
- IF ERRORLEVEL 2 GOTO NOTFOUN
- GOTO CONTINST
- .
- .
- .

-
- QEXIST.EXE was written in "C" and is a bound executable. This means it
- will run under OS/2 and DOS.

- Feel free to distribute this program and make as many copies as
- your heart desires, but you must not alter the program in any way
- and you must distribute this documentaion file unaltered.

- If you find this utility useful, all I ask is that you send me
- $5.00 for my effort.
