I don't think so - simple index - two character fields - purchase order, and customer number. I thought the file was corrupted, so I made a completely new one, index and all. I can stuff it with 32767 records, and then add one record in the prg, and it bombs. Recreate the file, stuff it with 32766 reords, add two in the prg, and it bombs. Never seen anything like it. Just will not go beyond 32768 records.
