Re: How to determine if a program is being run

I create/use a data area when the specific program is called,

If the data area exists (same name as pgm) I pop a message w/ user/time
about it being in use.


Another way is to have a permanent data area for each program, and use IN *LOCK when the program starts and UNLOCK when it ends. If the IN *LOCK fails, it's in use. Some programmers loop on the failing IN *LOCK some set number of times before failing out.
