Kind of a moot question since MS doesn't seem interested in allowing VFP to exceed the 2GB limit on file sizes. Anyway, I'm dutifully installing VFP 9.0 which will do me good for the next few years. For what I do, credit card payment processing, 16 bit is fine, 32 bit sounds good but isn't necessary, 64 bit would be mostly hype.
JMHO,
Scott
