Help me, about 2D x,y

Blitz3D Forums/Blitz3D Beginners Area/Help me, about 2D x,y

What I meant was,

example I place a circle at x5000,y5000 and the screen appears at x0,y0 if I press up the screen moves up, down the screen moves down(like scrolling,left the screen moves left and right the screen moves right, but the circle doesn't move the screen does :P

Another question, if I added a space background and like my spaceship goes right, so the background scrolls left at a certain speed, how would I do that? is that doable?
