EMPTY() is not Rushmore optimizable unless you add an INDEX ON EMPTY(myfield). That is a non-discriminating index. If you already have another index on myfield like this... INDEX ON UPPER(myfield) TAG xmyfield
then the following will work.
lcSpaces=space(len(myfield))
SET FILTER TO UPPER(myfield) # m.lcSpaces
You won't need a new index and it will optimize.
