Hello all, I got a lot of ideas for knowing when job starts and ends. Thanks for time and effort. Unfortunately, not answering my specific need, which is very rigid - I can't get into job logic, neither change it. the idea of getting a message from the system came from other OS - IBM's AS400 where the Job Queue sends a message queue to whoever wants when job ends. I assume there isn't something a like in the HP3000. Noam.
