The 2nd meaning of move is "animate". Our sprite skated right and left, but we'd rather have him walk. SPANIM is your friend. Try Line 4 yourself. Ignore the meaning of 0,"I" but the 6 means to switch to the next sprite in 6/60 sec like a flipbook, and the final 0 means to repeat back and forth infinitely. Now incorporate this to your buttons. Use WHILE...WEND since it's cleaner than GOTOs. [tbc.]
