Tom,
The limitation is actually 255 characters. If you make a to equal 255 characters the function works. At 256 it fails.
However, if you make the characters different like this:
a=REPLICATE("X",100) + REPLICATE("Y",100)+REPLICATE("Z",100)+REPLICATE("Q",100)
?ATC("Q",a)
Then the ATC command correctly returns 301.
Apparently there is a limitation
if the characters are all the same. I'd guess that internalls VFP parses the string to separate 255 length 'sub' stings.
