   RESOLUTION width, height

This keyword allows to have a “virtual” resolution. Even when you select a graphical mode with only 160 pixel x 200 pixel, the graphical instructions execute the same thing, the only difference is that the pixels will be proportional to virtual resolution. The choice to add this instruction is guided by mathematical ratio, since 640×400 pixels gives 1,6 where 640×200 gives 3,2. 1.6 isn't a perfect 4/3 ratio but at least it's closer. By default, the virtual resolution will be set equal to the resolution given by BITMAP ENABLE. Then, after RESOLUTION, the graphical instructions will use this virtual resolution.
