RE: Trigger?

[CWilt@xxxxxxxxxxxx]

Sure, you can use a trigger.


The trick is to use a before update (and add?) trigger and update the "after
image" buffer passed into your trigger.

***you can't do normal I/O from the trigger to the file the trigger is
attached to.  You must update the buffer passed to your trigger.

Also, you need to define your trigger with ALWREPCHG(*YES).
