If you are reading the entire subfile, try WRITEing the control record
before your second read through.

Thanks,

...using READC and SFLNXTCHG to process SFL entries.

...validate routine comes first, use READC, update SFLNXTCHG, finish READC
loop.

...if user presses update function key, code falls through and tries to
READC through SFL again to process only records changed for update.

Problem: second READC loop appears to already be at EOF when starting new
READ's (from previous loop?). No records processed, EOF reached
immediately.
I know with physical files, we can *LOVAL them back to the beginning and
read them all over again.

Question: Does OS400 support 2 READC accesses within same coding loop (only

1 EXFMT taken originally)? Is there any way to do this by using READC?
There
are multiple other methods to handle the updates but I am only interested
in
using 2 READC loops upon one function key depression.

Thanx for the time.
