Hi ... I'm not comfortable with "Arg FN FT FM . (", since it allows the
user to enter an invalid call.  I'd lean toward something like:

     parse arg ArgString
     parse var ArgString FileName '(' Options

and then testing "FileName" for validity (and too many tokens) before
moving on and testing "Options".
