I had a model trigger program published last year in a publication called
'Inside V3R1'.  You can contact The 400 Group at 617-444-5755.  The code
that you are talking about doing is not hard to write.

Alternatively, Data Mirror (Canada) has a product that does this today,
based on journaling.  This likely will have less AS/400 CPU overhead.
Mimix is expected to have a comparable product within a year.
