That might work, however we would also need a procedure to set the dataarea
back to a "no uncommitted changes" status after the commit. So if we forgot
that.... We might be able to change the dataarea back with a user defined
commitment resource, but this is overkill. Hopefully, IBM will give me the
API I need in a future release (PTF??) since all the info I could possibly
want is in the commitment definition already.

  Well, how about a Trigger program that sets a flag in a data area or a
message in the Job's Message Queue, either of which can be checked for
before the job ends or as needed, without major mods to the existing code
stack.
