So long as we're talking native RLA, then yes. That's how the index

Ladies and Gentlemen:

I have a file that is *not* uniquely keyed (the designer is apparently
ideologically opposed to allowing the OS to enforce uniqueness).

In my general observations, it has always been my *impression* that if
I'm going through a file in keyed sequence, via native RLA, records with
duplicate keys are presented in RRN sequence. But I am not certain of
that (and conversely, everything I've read about SQL-only databases like
MySQL says that the sequence in which records with the same key appear
in a result-set is neither predictible nor even necessarily repeatable).

But this is strictly DB2/400, via native RLA: If I am "Riding The RPG
Cycle" through the file, and I hit two or more records with the same
key, *can* I reasonably expect them to appear in ascending RRN sequence?
