Interesting.

The ILE RPG code equivalent to the point of failure,

FHPADLPUA IF F 1243 DISK
D RECORD DS 1243
C 1 SETLL HPADLPUA 121314
C READ HPADLPUA RECORD

exhibits exactly the same behavior as the failing MI program.

What's even more interesting is that without the indicators on the SETLL, the version using the DDS LF crashes at that statement!

Hmm.

*IN13 is the one that gets set on, so it's an error condition.

Hmm.

I just tried inserting a SETGT into both versions of the test RPG, conditioned on *IN13. They also returned with error conditions, on both the DDS LF and the SQL VIEW, and once again, the READ on the DDS LF worked, but the one on the SQL VIEW didn't.

So it seems that on a DDS file, we're protected from being left at an undefined position, but not with an SQL file.

Could this have something to do with the whole business of DDS files checking data validity on READ, but SQL files checking them on WRITE?
