Re: Triggers

[David Duerr <#ymcausa@xxxxxxxxxxxxx>]

Actually, you do not need the second step.  The record will be updated with
the updated new record
image in the trigger program.  Your method will work, but the second step
is unnecessary.

In the trigger program, use %subst to move the new record image into an
externally described data
structure with the definition of the file that fired the trigger.  This
makes updating fields in the
image a lot easy.  To apply the changes move the external data structure to
the new record image with
another %subst.
