RE: READC - OS400 issues?

["Richard B Baird" <rbaird@xxxxxxxxxxxxxxxxxxxxx>]

Dave,

Yes, it surely works.

You can set the rrn to pretty much any number, and readc and it will
re-position the cursor - as long as every time you readc, you update it
with sflnxtchg in effect.  If you only do the readc without update, you
won't get any reads on the second pass.

No kidding - does that really work?  When I need to read a subfile twice in
succession, I usually do the READC for the first loop and then a CHAIN for
the second, incrementing the subfile pointer until I run out of records.
If
your method works, that would be a much better way.

Hi Rick,

Before the second read of the subfile, set the RRN field for the subfile
(as
declared on the SFILE on the F spec) to 1 - it is the eqivalent of SETLL.
