ONE of those pairs must be wrong, since the screen isn't 321 × 241. The same bottom-right coordinates of 320, 240 are also cited on page 642.

You're right, that's wrong, and that paints a completely different picture on this description. I mean, who would have even thought there would be any errors in the manual?

To the trained eye, as anyone can plainly see, the top left coordinate is (0,0) and the bottom right coordinate is (319,239), totaling (x,y) = (320,240) pixels:

Code:


EXPORT PIX()
BEGIN 
  RECT();
  PIXON_P(0,0,#FF0000h); 
  PIXON_P(319,239,#FF0000h);
  WAIT;
END;
