Re: Join-logical (accessible via an RPGLE CHAIN statement) keyed across two different PFs -- any way to do this?

My situation from my original question ("The story you are about to see
is true; only the names have been changed, to protect the innocent") is,
for reference:

Got a couple of PFs. Call them FOO and BAR.

FOO is uniquely keyed on fields HAM and EGGS, and contains additional

field SPAM (which is the unique key of logical FOO_1

BAR has a field, FROTZ, the first key on logical BAR_1, that ties every

record in BAR to a record in FOO. And it also has a field, BLORB, which is
a date.

And I'm trying to check the latest BLORB for any given HAM. Not just for
one HAM, but for all possible HAMs.

Turns out (to my surprise) that just going through all the FOO records
for a given HAM value, and checking a logical of BAR by FROTZ and
descending BLORB, does the job, at a more than reasonable speed, even
repeating it for all possible HAMs.
