_DISPLAY turns off the automatic display of the screen graphics (which is at around 30 fps) while displaying the screen graphics. You have to call _DISPLAY each time you want the screen graphics to be displayed if you don't re-enable the automatic display by calling _AUTODISPLAY.

- x = x + dx: y = y + dy
- IF x < 0 OR x > 320 THEN dx = -dx
- IF y < 0 OR y > 200 THEN dy = -dy
