It is available by anonymous ftp as /pc/ts/tsdraw10.arc from the University of Vaasa, Finland, site 128.214.12.3. DRAW LINEs, Copyright (c) by Prof. Timo Salmi, (Ver. 1.0) 18-Jul-89 Address: University of Vaasa, P.O.Box 297, SF-65101, Finland Email: InterNet: ts@chyde.uwasa.fi (preferred) FuNet: VAKK::SALMI BitNet: SALMI@FINFUN 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.
