RE: Triggers

There are few, if any, "gotcha's" with triggers.
1) A file that is triggered can not be cleared.  That is, it can not be
the target of a CPYF or CLRPFM command.  If it has to be cleared, it can
be done with a SQL delete or through stick build RPG.
2) I would strongly suggest that your trigger program be a CLP.  That
is, have a CLP nammed as the trigger program and have it pass the
trigger parameters to a RPG routine.  That way you can make changes to
the RPG without having to get a lock on the actual trigger program.
3) Be carefull about cascading triggers.  It can effect performance.
Remeber the update that pulls the trigger is not complete until the
trigger program completes.
