Lets say I successfully chain and get Jack's record with a field NAME = 'Jack'.   Then lets say next up is Judy, and we chain to the file and no record is found.  What is the value of the NAME field in my program?  I guess what I am asking is, because of this coding, does that suggest there is an unrecognized  downstream problem?

I've been working with what I would consider a bug in a vendor supplied
program. They're processing a file conditioned on an optional field in a
secondary file. The secondary file is specified as input-only, externally
described, and keyed. For each record in the primary file, they do a chain
to the secondary (input-only) file. Then the code is something like:


chain (keys) secondary-record;
if not %found;
clear secondary-record;


In the ILE RPG Reference Manual under Initialization Operations, it reads:

"When these operation codes are applied to record formats, only fields
which are output are affected (if factor 2 is blank) or all fields (if
factor 2 is *ALL)."

Also in the manual under "Clearing Record Formats" and the CLEAR operation

if *ALL is not specified, only those fields with a usage of output or both
are affected. All field-conditioning indicators of the record format are
affected by the operation.

So am I correct in getting back to the vendor and telling them they aren't
coding the CLEAR incorrectly? i.e., It should be coded:

clear *all secondary-record;
