Re: Monitor for existing job.

["Dan Bale" <dbale@xxxxxxxxx>]

Rob,

Perhaps I should have described the presumptions I was making.  Obviously, the 
best way to make the data area lock work as we're looking to here is to lock it 
at the very beginning of the program, before any files are opened if necessary; 
if the program can't get an *EXCL lock on the data area, then RETURN with LR 
on.  So, yes, the program would be called in the subsequent job(s), but would 
be cancelled in short order.  I think that's about the best we can hope for.
