Bob,

you can retain the SFLNXTCHG attribute of any SFL record detected by a READC
by simply re-updating the record with the SFLNXTCHG indicator *ON.
This way any subsequent READC will always pick up the changed records.

 On occasion, I have to process the same subfile more than once in a single
 pass (prior to the next EXFMT).  READC retrieves the changed subfile
 records, but even with SFLNXTCHG, these records are only retrieved once
 prior to the next EXFMT.
 
 Obvious solutions to this problem:
 
 *      Read the full subfile and compare before/after values (with hidden
 fields) for changes.
 *      Save RRN's after initial READC into an array, and use this array to
 chain back to the subfile for future reads.
 *      Change logic to not read the subfile multiple times.
 *      etc.
