Jon,

Thank you very much for your message. I will leave the DELETED tags alone then.

>If you choose to SET DELETED ON, every table should have an index tag with a key of DELETED(). Rushmore uses the tag to optimize elimination of deleted records. Otherwise, result sets have to be checked sequentially for records marked for deletion. It doesn't matter whether or not any records are actually deleted. Only the SET DELETED choice matters.
