You have something in dos called errorlevel that will give you the value
you exit()ed with. This could be used in a batch file like this...

.	REM RUN MAIN PROGRAM
.	MAINPGM
.	IF ERRORLEVEL 0 GOTO GOOD
.	IF ERRORLEVEL 1 GOTO BAD
.	IF ERRORLEVEL 2 GOTO HAWAII
.	:GOOD
.	ECHO WE GOT A GOOD RETURN
.	GOTO END
.	:BAD
.	ECHO WE GOT A BAD RETURN
.	GOTO END
.	:HAWAII
.	ECHO WE ARE GOING TO HAWII
.	:END
.	EXIT

the number following 'ERRORLEVEL' will be the number you exited with.

Hope this will help...
