Re: Subfile processing question

One more reason to move away from READC and SFLNXTCHG and all other keywords designed for 300 baud modems. Just loop through the subfile, reading every record. Quick, reliable, and allows various options not otherwise easily available.

In the SFL pgmA, I am looping thru a READ NEXT MODIFIED to grab the
next changed SFL record.

Using STRDBG, the OPTION field that should contain '5" shows only blank.

When pgmB returns to pgmA, do I have to somehow reset the SFL cursor
back to the top? Or something else?

Something else. If you want to read a changed record more than
once with a READC (after a subsequent EXFMT) then you need to set the
SFLNXTCHG indicator on and rewrite the subfile record the first time
through.
