Re: Subfile Next Changed

Bob,

You should not need the write of the subfile control record. An update
of a subfile record with SFLNXTCHG on sets the "changed flag". Setting
RRN to 1 and issuing a READC should read the "changed record".

As to the RRN of 998 - are you sure there are actually 1000 records in
the subfile (as opposed to a size of 1000). At the end of your loop, X
would be 999 but RRN would be 998 if there were only 998 record in the
subfile.
