A previous message gave a method for converting a string to all upper case. It
will work, but it's slow and generates *tons* of string garbage, especially if
yuo are doing frequent conversions.  Here's a method that will work a bit more
rapidly, and won't generate any string garbage at all.  It works in DOS 3.3 or
ProDOS.

CAVEAT:  The string to be converted must be the last string referenced before
         this routine is called... even if you have to do something like
         "S$ = S$" before calling the routine.
