Re: Question About DDMF

Since the record "must" be placed in the buffer prior to
the update, I don't believe you can actaully do a update
with no read. The IOP is going to move the record into
the program no matter what method used.

Just because you didn't execute a read doesn't mean it
didn't happen. In fact, with "keyed access", you get at
least two reads as I recall.

I.e.. Keyed Delete/write.  That way you are only sending the record
across comm. once.
