13 ;"Although this XGF system allows for off-screen coordinates, the underlying
14 ;" M systems will not. So trying to position cursor to (-4,-5) MUST result
15 ;" in cursor being put at (0,0). This may be worked around by not depending
16 ;" on the current $X,$Y for writing etc. Instead, always specify coordinates.
