All of the above return either an integer for their value (fat(), frat(), foccurs()), or it creates a new fast string and returns the handle to it (which is also an integer).

FSTREXTRACT() might be an exception. It might make more sense to have it return a VFP string. I think I'll an option for it, that if set will return a VFP string, otherwise it will return a new fast string.

Part of the goal of fast string is to process quickly very large strings.

I think it might also need FALINES(). Will have to think about that.
