Trapping an sqr program status in a dos batch file

[Jason Maurer <JMaurer@WIREDEMPIRE.COM>]

As part of my daily production, I need to be notified when an SQR job
fails.  If the job fails I will need to send out an e-mail with some
sort of error message.  We are submitting our jobs through Batch Job
Server (BJS) on a Windows NT 4.0 workstation and using SQR (for NT)
version 4.0.3.  The BJS process used a dos batch file to submit the sqr
program via the dos command line.  If the BJS batch job fails (can't
connect to the server or a manual termination) there is an automated
procedure that kicks off to warn us that an error occurred.  If the SQR
program fails, the BJS process just keeps going and successfully ends
when it gets to the completion of the batch file.  What I need to do if
trap any sqr errors that occur and then evaluate them (in dos) and
hopefully kick off some sort of notification process.  We have a "blat"
process set up to send the notification e-mails.  I just need to know
how to get the sqr error status from the sqr program and then evaluate
it in dos.

Any help would be appreciated.
