>I have been getting some conflicting results in my code and want to make sure that SCAN .. ENDSCAN does not respect current index tag, right? That is, if I set new values in the field of the currently selected index TAG during the SCAN .. ENDSCAN the record pointer will not move back or forward but rather will go through each records.
