Should have said "see the access paths".

IIRC, you'll get them back in the order of the underlying access path,
regardless of the keys specified in the logical. So if the access path was
Field1+Field2+Field3 and you were reading through a logical keyed Field1
you'd still get them in Field1+Field2+Field3 sequence.

Thanks for the follow-up, Walden.  I still wonder if this is a new "feature"
or not, but icbw.  However, that is inefficient design no matter what.  I
can't imagine it would be ALL that difficult, when LF_B is created to switch
the *ACCPTH for LF_A to use LF_B.  Yeah, locks, but it could be done at IPL
time if necessary.

What do you mean "see the indexes"??

Good point about FIFO, etc.  I've never tried, but would READE on LF_B and
LF_C be retrieved in FIFO or in order by Field2 (which is what I would
guess)??

| Also, remember FIFO, LIFO, FCFO are all considered "keys", to get sharing
