Sun 16-Dec-90: I have updated my linear programming and linear goal programming package to be /pc/ts/tslin33.arc. Here is an extract from the release notes of the documentation: Version 3.3: Version 2.6 introduced the possibility of selecting the foreground and background colors of linsolve by applying /f# and /b# switches in the program call where # means a color number (0-15 for foreground, 0-7 for background). I have made several improvements. The forground and the background color can no longer be made equal to each other. Giving an out of range value is now trapped by the program. Most importantly the color codes can now be optionally given as color names (Black, Blue, Green, Cyan, Red, Magenta, Brown, LightGray, DarkGray, LightBlue, LightGreen, LightCyan, LightRed, LightMagenta, Yellow, and White). After having not used linsolve for a spell myself, and needing to change the colors for an overhead projector session in a classroom situation (I got squarely stuck for a minute), I decided to make these improvements. The normal maximum width of a simplex tableau is 79 characters which means presenting six columns of figures per row. I have added a switch /c# to the program call where # can range from 1 to 15 columns. This means a choice of a wider (or a narrower) output than the standard screen. This switch is operative in registered versions only. When output is directed to the printer, the program checks that the printer is online. The method I used earlier fails on some printers, so I adapted another method which is hopefully more robust. Updated the list of references (Chapter 10 of the instructions).
