   Dik T. Winter (dik@cwi.nl) and I have been discussing via e-mail 
   the standardization of user input signals, and I came up with
   a 9X proposal for general discussion:

      o Have one generic standard I/O package for 8-bit character sets,
        and another generic for 16-bit character sets, which could then 
        be instantiated for the appropriate character set.

      o Have one 16-bit and one 24-bit standard character set which
        serve to represent the concept "User Input Signal".  If the
        particular value of the User Input Signal is, for example,
        an arrow key or a mouse button, then the program can react 
        to that signal and loop back for the next one.  If the signal
        isn't a control signal, then a type conversion can be done to
        convert the signal into a standard CHARACTER for storage.  A
        User_Input_Signal could also be stored directly if desired.

   Comments, anyone?
