Kev,

The performance hit isn't from having the index, it's from FoxPro retrieving the index across the wire when you access the table. Without the index it goes right to the records you need, gets them, and then checks those few locally for their DELETED status.

The best thing for you is to read the FPA article from last Spring about 4 times! ;-)
