you could do it either way but it would probably be more manageable to make a seperate function. You could have : int run_menu(ALLEGRO_DISPLAY *display, ...whatever \else you need...) { } ...and use the return value to decide what to do back in the caller.

Which part is not understandable to you? " There are plenty of wonderful ideas in The Bible, but God isn't one of them." - Derezo |
