Re: Subfile processing question

I have also stopped using SFLINZ and SFLRNA in favor of SFLCLR. That way I can easily keep track of what is in the subfile myself and not rely on record not found errors to tell me when I have read the entire subfile. This has an added benefit of avoiding all the record not found errors being put into the job log. Makes it easier to use the auto-load message subfile too as I don't have to contend with those superfluous messages.

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.
