>My assumption is the block of code between the FOR EACH (...) NEXT get compiled and executed in ASM or C while the code between the FOR (...)NEXT get compiled and executed in VFP. This would make the FOR EACH considerably fast when acting upon a grid with many columns OR a form with many controls - am I right?

Hi tim,

As the others have mentioned, because VFP use tokenized p-code, there's no difference in the way the code is run. FOR EACH, however, is actually slower, by about 40% in my tests. I would assume that this is because of the implicit assignment to a variable that occurs.
