Simple Chipmunk Physics

[Cybermonkey]

Okay, I guess I can initialize chipmunk, but again... In demo11 the drawing is done by

  cpDrawSpace( space, TRUE );

which means I have to "break down" the source of ZenGL. What if I would add a "ball" with your procedure

procedure cpAddBall( x, y, r, mass, e, u : cpFloat );

how do I know where to draw the circle when physics were calculated. Assuming my procedure looks like

circle (x,y,radius)

and my engine is purely procedural driven which means I have to establish a game loop like

repeat
  key=getkey();
  //do all the stuff
until key=27;

How can I get the x and y value of my ball?
