Re: RRN Reletive record number question

Jim Franz,
I know of what you speak. You're saying that a CHGPF, specifying a source
file so as to add new columns, may reorder the rows. A technique that's
been out for decades yet some still do not know of it.
Is this potential reordering of rows due to this:
1 - An assumption
2 - Documented somewhere
3 - Something you experienced?

a CHGPF that internally executed a cpyf like function might also alter the
order, and some of that may be dependent upon how physical and logical key
options are specified.
You may say you will never reorg, but who knows in the future when you may
need to CHGPF. I've only had need of RRN inside a single process of
imported data determining dup rows as a way to differentiate,
