Move can mean 2 things and I assume you want to learn both. Let's start with the easier one: position change. Simply add X=X+1 for the right button and X=X-1 for the left, then add +X to your SPOFS to reflect this change. So if you press right, character moves to the right by 1 pixel per frame, same to the left. I recommend VSYNC over WAIT because of less problems. [to be cont'd...]
