If so then you could use something like this, although I really hope there is a better way.

Code:

EXPORT RQST()
BEGIN
FOR Y FROM 0 TO 239 DO
FOR X FROM 0 TO 319 DO
IF (X-120)^2+(Y-120)^2<80^2 THEN
PIXON_P(X,Y,RGB(255,0,0));
END;
IF (X-180)^2+(Y-120)^2<80^2 THEN
PIXON_P(X,Y,RGB(0,255,0));
END;
 
IF (X-180)^2+(Y-120)^2<80^2 AND (X-120)^2+(Y-120)^2<80^2 THEN
PIXON_P(X,Y,RGB(0,0,255));
END;
 
  
END;

END;

END;

I ask you a question, do you have an example of use, how can I enter several variables? How can I discriminate by UNION, INTERSECT and DIFFERENCE? thanks again for sharing
