    procedure sf_cua_udf_icon prototype
      parameters value int char_number,;
                 const char( 8 ) byte_one,;
                 const char( 8 ) byte_two,;
                 const char( 8 ) byte_three,;
                 const char( 8 ) byte_four,;
                 const char( 8 ) byte_five,;
                 const char( 8 ) byte_six,;
                 const char( 8 ) byte_seven,;
                 const char( 8 ) byte_eight,;
                 const char( 8 ) byte_nine,;

                 const char( 8 ) byte_thirteen,;
                 const char( 8 ) byte_fourteen,;

                 const char( 8 ) byte_sixteen

    The Special Forces library relys heavily on redefined fonts.  This
    function allows the programmer to define his/her own icons.

    Example:

    sf_cua_udf_icon( 219,;
                     "00011000",;
                     "00011000",;
                     "00011000",;
                     "00011000",;
                     "00011000",;
                     "00011000",;
                     "00011000",;
                     "00011000",;
                     "00011000",;
                     "00011000",;
                     "00011000",;
                     "00011000",;
                     "00011000",;
                     "00011000",;
                     "00011000",;
                     "00011000" )

    Note: The 0's of the structure are left blank and the 1's draw the
          font.  This example would make chr( 219 ) look like an up/down
          line.
