RE: SFLNXTCHG

John,
I think you may have hit on it. The subfile is in-effect being used as a work file. It is a complex JDEdwards World A7.3 program being cloned to run on a hand-held data collection device. The subfile is being updated from input on the hand-held but the control record does not get written again before trying to process the subfile as though the ENTER key was pressed...I will try this and see...THANKS

Have you tried setting the MDT on?

Right. To finalize the setting of SFLNXTCHG of being "on", you must write the control record, not just update the subfile. You are updating the subfile record when you're setting SFLNXTCHG on, right? You're best be is a loop with a CHAIN.

Actually your best bet is to use a DS Array. Much less overhead.

Hi Chuck
Maybe I'm misunderstanding what you are saying/asking If the subfile
is never displayed, how could something be changed to use READC (read
changed) If you need to read the subfile, it would be better to CHAIN
to the data by relative record number

I have an application with a subfile which is not displayed on-screen but utilized in the background. It would appear that the READC op-code is not working, even though the records were updated with the proper indicator for the SFLNXTCHG keyword.

Does the SFLNXTCHG/READC not work if the subfile is never displayed on-screen?
