Draws lines in a window.
disp_line displays one or several lines in the current output window. A line is described by the coordinates of the start (Row1,Column1) and the coordinates of the end (Row2,Column2). The procedures used to control the display of regions (e.g. set_color, set_grey, set_draw, set_line_width) can also be used with lines. The output window is set with the procedure set_window. Several lines can be displayed with one call by using tuple parameters. For the use of colors with several lines, see set_color.
The starting points and the ending points of the lines must lie within the window.

disp_line returns TRUE, if a window is activated and the parameters are correct. Otherwise an exception is raised.
