>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.

Never heard of anything like that either.

Any foxuser.dbf. Sometimes the get corrupted. Try building a new form and grid and access that table. Maybe the form or grid has a problem. 32767 is one of those magic numbers. Are you doing anything fancy like tracking relative positions of the records and that routine is failing?
