Hi glenn,

I know i'm stepping on ice, but when seeking records on more than one criteria, a SET FILTER in combination with SEEK can be far faster than a optmizable LOCATE. However, performance depends on the selectivity of the FILTER.

Walter,

>Seek cannot be beat for data retrieval based upon a single index expression. If you need to retrieve data based upon multiple optimized expressions the use either locate or SQL-Select.

>Selecte * from MyTable where state='MI' and city='TRAVERSE'

>>As Alex has said Locate can be as effective as Seek, however, you need to be very careful and ensure that your statement is Rushmore optimised or you will have a performance hit.

>>Locate is powerful in that it will sequentially read through a table if it can't use Rushmore, however the downside is that it can be very slow.
