>As Perry said you can't have variable length indexes. AFAIK bytes 12-13 in index header keep key length. It should be fixed for a key. I don't have an idea how would fox index with trim() and first entry had only one char (I think it would be ignored and field size used).
My Educated guess is that the key lenght would be based on the contents of the first record in the table (recno()=1).
