O_NONCYCLIC
    Don't wrap around next-item and previous-item, requests to the other end of the menu.

O_MOUSE_MENU
    If user clicks with the mouse and it does not fall on the currently active menu, push KEY_MOUSE and the MEVENT data back on the queue to allow processing in another part of the calling program.

E_OK
    The routine succeeded.

E_SYSTEM_ERROR
