is this the entire program??  if so, you need to add a "ret" statement
or else it will try to execute the bytes at A_shape as code.  also,
why do you switch the page to 0 "out (5),a"?  i don't know why that
would be necessary.  also, you would want to add something to allow
you to see the sprite (see below).
