Re: Multi-threading

Well Venu, since they solved your "multi-thread" problem, maybe you would like 
to try
triggers. If PF1 only contains records that will cause jobs to be submitted, a
trigger program can be written and attached to the file. When a record is 
added, the
trigger is notified (You can specify before or after the record is writtten). 
The
trigger program could then submit the job.

Might be a good introduction to triggers.
