The difficulty with this approach is that the trigger must be a *BEFORE
or*AFTER timing.  If it's before you can definitely determine that the
insert/update/delete shouldn't occur but I don't see how you can prevent it.
Remember the trigger gets copies of the output buffer from the program
causing the trigger to fire.  If you use a *BEFORE trigger, upon return to
the I/O processor the original action will occur.  If you use an *AFTER
trigger, the operative work is "AFTER".
Using an *AFTER trigger, you could go back and reset the orignal state of
the record because the trigger does contain the before picture of the
record.
