Why, said the Dodo, the best way to explain it is to do it. (And, as you might like to try the thing yourself, some winter day, I will tell you how the Dodo managed it.) Lewis Carroll, Alices Adventures in Wonderland, 1865 The following notes are adapted from the GAUSS manual, GAUSS, Mathematical and Statistical System: Supplement for OS/2 and Windows; Vol.1, System and Graphics Manual; Vol. 2, Command Reference, Maple Valley, WA: Aptech Systems, 1984-96. I make use of a series of small GAUSS programs, basic01.gss through basic26,gss, to illustrate commands and manipulations. The programs and the output from them are reproduced as an appendix to these notes. The programs and the data necessary to run them are available at the homepage for this course: /gauss/gauss.htm. If you are working on the AREC network, you will need to establish a working directory on your local machine. GAUSS is k:/Gauss32/gauss.exe. You can set up a shortcut with k:/Gauss32/gauss.exe as the target; the working directory is whatever you fill in the “Start in” box. I use c:/files/gaussfls for example. GAUSS does not recognize file names of more than 8 characters. You can also set up folders and direct output other than graphics to specific locations on your local machine. Graphics are not specifically addressable; graphics output will appear in your local directory with a tfk tag. CONTENTS 1.GAUSS/WINDOWS INTERFACE; BASIC STRUCTURE OF A GAUSS PROGRAM 2.
