>That's true. However, I'd bet if there were a large # of deleted records at the top of the table, the initial USE of the table would result in a period of thrashing as VFP tries to navigate to the first record.

Sure, and there are other instances where inefficiencies arise - like lacking indices. I just wanted to clarify that - according to my understanding - it is not true that invariably, the entire table is transferred.
