Charles,

Got it...like I said, I was being dumb :)

I think my test showed that SETLL is losing when the search criteria is after the largest key. Interestingly, that's the only time it would have to be repositioned as well, right...

Crispin,

Sorry, I wasn't clear. How's this: chain is faster only if the key
being searched for
doesn't exist AND the key _being_searched_for_ is greater than
anything else in the file.

According to the message from Barbara that you posted the ink to, this
is due to the fact that SETLL has to reposition to the EOF. Whereas
chain doesn't.

Your message does make me wonder...what if the file pointer is already
at EOF. Does SETLL still lose? Maybe your test showed that it does?

In any event, the test where the records exist is as I expected.

Charles
