   parameter allow special behavior. They are:
      - kAEUseStandardDispatch means redispatch as if the event was just
        received, using the standard AppleEvent dispatch mechanism.
      - kAENoDispatch means ignore the parameter.
        Use this in the case where the event has been handled and no
        redispatch is needed.
      - non nil means call the routine which the dispatcher points to.
