Hi foxgang
I just spotted a nasty. GetWordNum. If you have say aa ="A,B,C,,,F" and ask
for GetWordNum(aa,4,",") it gets it wrong. Seems it cannot handle blanks. A
pain as I just had some.

Personal opinion ahead...
Not sure I'd call that a bug...technically you are asking it to deal
with null, not blanks. If you put a space between the commas instead of
nothing, it works as you expect. Check out GetWordCount()...which acts
the same way...it 'ignores' the non-existant "thing" between the 3rd and
4th commas, and the 4th and 5th commas.
I suspect this was more of an intentional, but undocumented (at least in
the Fox Help) "feature" that had to be handled one way or the other.
(either ignore "nothing" or count it.)
But, it would have been nice had they offered a switch to include, or
not, and had documented this behavior.
So, while I wouldn't call it a bug in VFP, I would call it an
undocumented feature...which often masquerades as a "BUG!"
