Bruce,

I agree regarding the EXTK for alternate indices (logicals), but this is a physical with a single key field.

I re-compiled the program for debug (ISDB has a problem with /Copy books) so I know it was still using '1' as the key field's starting position. So there was no mismatch between source and object - in this case. I, also, changed the key start position to the correct location ('2') and the program still worked as expected.
The LISTCONS table is only used to verify a code entered on the entry panel, which is this program's raison d'etat.
For what it's worth, I created the table and added it to this program a couple of years ago so I am the one who accidentally mis-defined the key's start location.

According to the RPG II manual at http://publib.boulder.ibm.com/infocenter/iseries/v5r4/topic/books/c0918180.pdf non-contiguous fields are indicated by the value 'EXTK' and files with a contiguous key by the starting position.
Is it possible someone has changed the source and your executable is based on a previous version?

Hi Jerry,

Keeping in mind that my grey cells are leaking out and making my hair grey, but I have this recollection that when IBM started allowing non-contiguous key fields, the key location in RPG II changed to just 1, i.e. pretty much unused. I always thought of it as the position of the key in the index, not in the physical file, and in the index entry, the key would always start in pos.1.

I really don't expect an answer. In fact most people will probably just delete this when they see the subject line. But this is puzzling the heck out of me.

I went in to an RPG II program (old package) to do some simple maintenance changes. I noticed that one of the files was defined as:

FFilenameIPEAFBlenRlenLK1AIOvKlocEDevice+
FLISTCONSIF 27 1AI 1 DISK
Well, the key length is '1' but the key actually starts in position '2' of the record. The purpose of the file is to validate a code entered on a panel:

C WRCONS CHAINLISTCONS 54
C 54 SETON 99
C 54 *ZEROS ADD 23 $ C 54 GOTO X2A
The first position of LISTCONS is a status byte. Currently every record has an 'A' in position 1. The program has been successfully validating these codes for years. How is that possible? I even put the program under debug (ISDB) and verified the codes entered (WRCONS) and in the file (ABCONS) are the same after the chain, and that indicator 54 is turned *Off.

It has been awhile since I programmed on a S/36, but I'm pretty sure that, first, when the program started up it would give me a file mismatch error. Is the i5 really smart enough to say, "Well, he botched that. Let's just use what is really in the file."?

Thanks.
