Guys thank you very much for your answers.
C.pfaffenbichler, unless im given visual instructions, I'm not sure i can follow what you have written. Im way behind your skills. So i have to look for other ways. I have another question. If the rectangle was smaller, within the circle's boundaries and if we had the fifth mode - exclude. what would happen if we did A and B exclude? When I intersect A and B, I get B. Would I get A (without the star) if there was exclude mode?
