Yes, ALLTRIM() removes spaces from the value but it does not reduce the size of the index key. As I pointed out in the earlier message, an index key in VFP have fixed length. As result the value get padded back with spaces to the length of the index key.
The UPPER() function OTOH can reduce the number of values in the index.

>Hmmm, alltrim() is supposed to remove blank spaces, which would reduce a file's size. Upper does not, so how would upper() make a file smaller?
