	As far as I can tell, it's up to you.  The "F" functions are probably
a bit faster, since they're just #defines that jump you right into the system
stuff; the "f" functions, while it is true that they're more compatible with
other environments, will probably be a bit slower since they go through some
translation routines first.  However, any extra time that the "f" functions
take will probably be so small (as in less than a hundred machine
instructions) that it won't matter (especially since the functions take
forever, anyway, since they all need to do disk I/O).  Anyway, there's your
difference.
