Alternatively, our intrepid hacker may have seen:

     If POS (UpCase (ReadKbd), 'NQSR' <> 0 THEN
        CASE ...

or something similar. "POS" will produce a result similar to that
of a set manager, and in cases where you want to select from only
a small number of characters, it's more efficient.
