Syntax   Draw.Line (x1, y1, x2, y2, Color : int)

Description   The Draw.Line procedure is used to draw a line on the screen from (x1, y1) to (x2, y2) using the specified Color.

Example   This program draws a large X, reaching to each corner of the screen using color number 1. The maxx and maxy functions are used to determine the maximum x and y values on the screen. The point (0,0) is the left bottom of the screen, (maxx, maxy) is the right top, etc.

        View.Set ("graphics")
        % First draw a line from the left bottom to right top
        Draw.Line (0, 0, maxx, maxy, 1) 
        % Now draw a line from the left top to right bottom
        Draw.Line (0, maxy, maxx, 0, 1)

Details   The screen must be in a "graphics" mode. See the View.Set procedure for details. If the screen is not in a "graphics" mode, an error will occur.

Status   Exported qualified.

This means that you can only call the function by calling Draw.Line, not by calling Line.
