DRAWLINE is a graphics system for displaying and demonstrating
equations of two variables (that is lines) on an x and y coordinate
plane. In particular, the system has been developed for graphical
presentation of small linear programming problems, but it is
suitable for other line-drawing applications, too.

The system has it own command language. First call DRAWLINE. The
screen will be divided into two parts, the drawing window, and the
command window at the bottom of the screen. To draw a line, say
2x + 3y = 6, type the command li 2,3,6 and the line will be drawn.
There are many other graphics commands, and a number of calculation
commands, as well. The commands can also be entered from a file such
as DEMO.DRW. To list the commands type ? or help. For a full
description of the commands, see the document TSDRAW.INF.

To run DRAWLINE your computer must have a CGA, EGA or VGA graphics
adapter. The system applies four-color CGA graphics.
