Pretty basic notion, but I'm falling over on this...
With a sprite that has a starting X,Y and a speed, I'd like the sprite to remain on screen.
However:
-- locks sprite off screen after passing the screen boundary
-- if btn(0)
--and x<128
-- then//move sprite
-- if x < 128
-- then
-- x=x-speed
-- end
-- end
-- locks sprite centre screen
-- while x < 128 do
-- if btn(0) then
-- x=x-speed
-- end
-- end

the mid method is the simplest and uses the fewest tokens.
the if method allows you to insert extra logic such as playing sound effects when you hit the walls or bounce off or something.
the min,max method is equivalent to the mid method.
