Use This vector is used to indirect all calls to [[OS_WriteC]], and in turn [[OS_NewLine]], [[OS_PrettyPrint]], [[OS_Write0]], [[OS_WriteI]], [[OS_WriteN]] and [[OS_WriteS]] which call it. h4. Notes In practice these SWIs may not actually call [[OS_WriteC]] or this vector if there is no reason to do so (i.e. _the vector is not claimed, spooling and printer are inactive_). h4.
