            3) Graphic commands:
            --------------------
 
               PRINT #1:"D";x;y    line from cursorposition to

                                   ((0,0) = actual cursorposition)
               PRINT #1:"W";y;x    ellipse with cursorposition as
                                   center
                                   ((y,x) = length of semiaxis)
               PRINT #1:"H"        fills screen with actual color
                                   (used for clearing the screen)
 
 
            4) Text commands:
            -----------------

            Bit 5 of the control register no. 8 determines how
            color code 0 is displayed. 0 (default) means color 0 is
            transparent, 1 means color as specified in palette
            register no. 0 (MSB = bit 7).
