RE: Lock on command processing program ignored

["Dan Bale" <dbale@xxxxxxxxx>]

I have tried this before with the results you're getting.  ALCOBJ *EXCL does
not work on program objects per your usage.  To do what you are trying to
accomplish, you'll need to lock on to something that will "lock" (like a
file, does the program use a device file that only that program uses?)

This is our own command and program. I want to make sure only one job
can run it at a time.

There are no messages coming out in the joblog.

I will be trying an ALCOBJ *EXCL in the validity checker. I'm just
curious as to why a locked-exclusive CPP can still be used.
