RE: Use of regular expression

Jon is right, of course. I hadn't considered that aspect. My objection
(again, misapplied here) is to the "use SQL if you cannot figure out another
way" or "... because you can" approach.

I don't often disagree with Dennis but I suspect he may be wrong on
this one.

From what the OP said, the program would read each record and then
run the %scan/regex against the record. That means every record would
have to be surfaced in the program. Using SQL it will only surface
those that match the selection criteria - surely that has to be faster
unless a very high percentage of the records are hits.
