RE: Subfile Next Changed

["Fisher, Don" <Dfisher@xxxxxxxxxxxxxxxxx>]

I'm guessing there are only 998 records in the subfile, which means the
999th iteration of the loop is failing to access a subfile record.  That
would explain why RRN is 998 before the READC.  Perhaps setting RRN to 0
before the READC is all you need to do.

**NOTE SUBFILE SIZE is 1000.
When I look at RRN on pgm subfile rec after 999 loop and before readc it's
998?

READC to end loop? Might work but...

I thought write would do it. Do I need to force RRN to be 1 before write of
control record?
 Or will it reset? Other loops later use RRN for CHAIN, LOOP CNT,etc. on
subfile records.

Thanks Again,
Bill H

     yes you need to do a WRITE {subfile control record}
before the READC (this will effectively re-set the start point).
