FoxPro will not use your rfrom tag because the index expression, "rfrom", does not EXACTLY match the expression in your query, "alltrim(rfrom)". The SQL SELECT processor will probably create an index on "alltrim(rfrom)" on the fly, but that will take some time to create.

As Tamar points out, the SYS(3054) function can be useful in determining whether Rushmore has kicked in fully, partially, or not at all.
