POINT                    Attribute or Value of Screen Coordinate

 y = POINT({x,y | n})

    Returns the attribute of a specified screen coordinate or coordinate
    information about the current screen location.

         x,y    Screen coordinates (column, row). POINT(x,y) returns the
                attribute of the screen location specified by the two
                arguments. The screen coordinates must be given in
                absolute form (STEP is not allowed). If either coordinate
                is out of range, POINT returns -1.

           n    Must be 0, 1, 2, or 3. POINT(n) returns the following
                information about the current screen location:

                If n = 0      the current physical x coordinate.
                If n = 1      the current physical y coordinate.
                If n = 2      the current world x coordinate, if WINDOW is
                                   active; otherwise, the current physical
                                   x coordinate.
                If n = 3      the current world y coordinate, if WINDOW is
                                   active; otherwise, the current physical
                                   y coordinate.
