 There is also no SPC function in Atari BASIC.Advanced aspects of the hardware such as player/missile graphics (sprites), redefined character sets, scrolling, and custom graphics modes are not supported by BASIC; these will require machine language routines or PEEK/POKE statements.A few graphics modes cannot be accessed from BASIC on the Atari 400/800 as the OS ROMs do not support them; the only way to access them is in machine language by setting the ANTIC registers and Display List manually.
