Keep in mind, though, that when you do the READC, it will only read in records from the subfile that have had a CHANGE made to them. As an example, if you have written a bunch of subfile records out and have a one-byte input field at the front and the user inputs a “1″ (to select the record) into the input field on the third record of the subfile, then, when you do a loop to perform the READC, the only record that you will get will be the third record. If the user had entered a “1″ on the third and the fifth subfile record, then the looping READC would first read subfile record 3 and the next READC would give you subfile record 5.

MadDogDing is correct. Just remember that if the user uses the field-exit key to get to the 3rd and 5th records, they have changed — even pressing space to move through subfile records flags them as changed.

If you need to read all the records, even if they weren’t changed, you can use the SFLNXTCHG keyword when loading the subfile.

remember sflnxtchg is indicator driven.
so you can control wahat records come back.
I usually use a one byte hidden field to
indicate that the user has changed are added
something to a sfl record. I continue to
bring that record back while that sfl is
on the display. Say a sfl is 200 records
and the user touches only 6 of those records,
It’s better to bring back the 6 they touched
than all 200.
