- Sun 8-Sep-91: Updated my graphical drawing system for linear
- equations and Linear Programming problems to be /pc/ts/tsdraw14.arc.
- It is a complete drawing system with its own command language. To
- give a simple example you can draw the line 2x + 3y = 6 by giving
- the command li 2,3,6, and the line will be displayed on the
- coordinate system. The program has the options of entering the input
- from the keyboard or from a file. If the input is taken from the
- keyboard, the input line can now be edited (and recalled if need be)
- by using the usual line-editing keys CursorLeft, CursorRight, Home,
- End, BackSpace, Delete, Esc, and CursorUp. There are some other
- small enhancements, but this is the crucial in this update.
- The system is not actually limited to drawing lines, but that is
- what I use it for myself when teaching budgeting with linear
- programming in a classroom with an overhead projector to display the
- computer images of the relevant tasks (examples are included in the
- package). I also have a Linear Programming solution program
- /pc/ts/tslin33.arc which I use in a similar manner in teaching
- quantitative budgeting for my accounting and business finance
- students at the University of Vaasa.
- The drawing program requires at least a CGA graphics adapter but
- other than that there are no special requirements. The size of the
- drawing program executable is about 90K.
- To get started after you have extracted the files from the
- package, first call DRAWLINE at the MsDos prompt, and then give eg
- the command ld multibre to have a demonstration of a multi-product
- break-even analysis. You can also enter ? or help for a quick list
- of commands.
- The files in the package are:
