>>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?

Tokenized p-code, hum... something new (to me). Thanks to all that responded to this thread!
