RE: [EXTERNAL] Re: Quick question on file behavior

Has the file ever been re-orged (RGZPFM)?
How was it re-orged is then the question

Is reuse deleted records turned on, if so I highly doubt it.

What about a logical?

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?
