A FOR automatically rewinds to top, yes, but fox is clever enough to use index to find records for replacement with expressions like in your sample (I don't mean WHILE is a problem - whenever I saw WHILE fail it was my fault not Fox's).

Wow sort of a sub-filter with the speed of while, works with FPD?
