GetWordNum() and GetWordCount() don't seem to accept chr(0) as a word separator, while corresponding old functions in FoxTools still do:

x=STUFF(REPLICATE("x",33),13,0,CHR(0))
?x
?GETWORDNUM(x,1, CHR(0))
* both return the same, all 34 characters
?GETWORDCOUNT(x,CHR(0))
* returns 1
* With FoxTools:
?WORDnum(x,1, CHR(0))
* returns 12 chars
?WORDnum(x,2, CHR(0))
?GETWORDNUM(x,2, CHR(0))
* both return empty strings
?WORDs(x, CHR(0))
* also returns 1

* now we give it two null chars
x=STUFF(STUFF(REPLICATE("x",33),13,0,CHR(0)), 22,1,CHR(0))
?WORDs(x, CHR(0))
?GETWORDCOUNT(x,CHR(0))
* both return 1
?WORDnum(x,2, CHR(0))
?GETWORDNUM(x,2, CHR(0))
* both return empty strings

So, FoxTools is just a little better here - it will return the first word correctly. Since FoxTools in VFP7 is actually a recompiled leftover from VFP6, I expect the results under 6 to be the same.
