>........Yes you can use the FOR and WHILE clause in the LOCATE. What happens is only the records matching the initial SEEK value are searched for the Field2 value. So if you have 10 records that matched the first SomeValue, only the next 10 records are searched in the LOCATE. Can't get faster than that.

The first record found by the seek would also be searched because it meets the criteria in the WHILE clause.
