Rushmore has nothing to do with the power tools. Rushmore has nothing to do with your report layouts. Rushmore has nothing to do with your mouse or keyboard. Oddly enough, the design team came up with the code-name Rushmore after spending a night watching the movie North By Northwest . Any time you can include a for clause in a statement, Rushmore will try to optimize the expression.
Some exceptions apply.
For example, Rushmore will not activate if you have a statement with a while clause in it. You can utilize Rushmore in any FoxPro statement that allows a for clause, or in an sql statement. If you are dealing with databases of any size, you should utilize Rushmore as often as possible. Basically, if you can't include a for clause, you can't use Rushmore. Rushmore also can't be used if you have a while clause in your statement, or if you are doing a locate on the child table in a multi-table relation.
