>You might want to Optimize the FOR expression by indexing the table on the field 'posted'.

If "posted" has only a few values (like .T. / .F.), this will probably make the query slower, since, to "Optimize" the query, Visual FoxPro will get index information for all records that have the specified value.

UPDATE: Oh, sorry - looking back at the original message, the information the field holds is quite different. But creating an index had been suggested already.
