Reading the RRN of the original record or of  the subfile record?

I'd think you might rather update the original file records, not the subfile
 and then reload the subfile.  Updating the subfile itself, then later
needing to update the original records, could become a nightmare.

To reach the original records I might have the file's key as hidden fields
in the subfile.

Subject: Reading a control record in a subfile

I have a subfile that displays header information in the control record
then repetitive information in the subfile record. To update this
information a user may update any information in either of the records.
However, if only information in the control record portion is changed, then
I need to read through all of the subfile records and update each of the
correspondng PF records with the changed header information.

I was trying to chain to each record of the subfile using the RRN, then
move the changed fields to the PF fields and do an update. This does not
seem to be working. But a READC will not work either because the subfile
records themselves may not have been changed. I am not sure this makes any
sense in type...but if anyone has any ideas, I'd appreciate it. I looke
through the archives and could not find anything on reading just the
control record, or reading unchanged subfile records.

Thank you in advance.
