Re: RPG Cycle

Using the cycle with just a primary file is easy.  Using it with a primary
and a secondary file with MR is somewhat more difficult, especially when you
want to do updates as well.  But when you start using more than one
secondary file with MR, things start to get really confusing.  In your
example an invoice record with a matching detail record, but without a
matching header, would slip through: *INMR is on because of the match in
DETAIL.
