Could you please suggest right way to do the same.

Thanks. We'll let you know when a new response is added.

Hi,

Once you’ve used the READC the records are no longer “marked” as changed. You can either specify SFLNXTCHG on your subfile (which will mean that the records are *always* marked as changed) or you can use CHAIN with relative record number instead of READC to get your subfile records.

Regards,

Martin Gilbert.
