What does it mean: "klunky"? :) Yes, it's definitely "klunky" (or "klugy" :)) and would not work for generic purpose. I think, I would proceed with my original idea, which is similar to Lister's idea...

Anyway, thanks.

>I have an idea... Haven't tested it; just thinking... If you know all of the field names that have other field names which are part of them, temporarily change the larger ones, do the STRTRAN, then change them back.
