[revised August 1997] The Richardson 106 computers have now been equipped with software for viewing PostScript and DVI files. This will make it much easier for the mathematics faculty to display documents with proper mathematical typesetting. When you click on a Web link to a file with extension .ps or .dvi, Netscape should automatically call up the proper helper application. In the .ps case, you can then also send the file to the printer if necessary. PostScript is the standard control language for laser printers. DVI is the output format produced by TeX, the premier system for typesetting mathematical material. Most often a .dvi file is converted to a .ps file before printing. However, .dvi files are smaller than the corresponding .ps files, so there are advantages in download time and disk space in using .dvi files directly for Web display. See the next message for help in using CDVI. To get these programs for your home computer: [as of spring 1997] The Ghostscript/GSview system is a standard, freely available item. Go to the site http://www.cs.wisc.edu/~ghost/ and follow the links "Obtaining Aladdin Ghostscript 4.03" and "GSview previewer for OS/2 and MS-Windows". If you are not experienced in unZIPping and installing fairly complicated software packages, you will probably want some help. Make sure you have about 10M free disk space. At the final step, you have to configure Netscape to find GSview, using the Options...Preferences menu. CDVI may be used freely by students and faculty at Texas A&M, but they may not redistribute it to others. A $1 donation is requested if you like the program. (Address: n^2 Computer Consultants, c/o Norman Naugle, P O Box 2736, College Station, TX 77841.) I (Stephen Fulling) can provide you with two diskettes containing self-extracting ZIP files to install CDVI, along with installation instructions and a page of documentation. You need about 2 megabytes for CDVI. Another freely available DVI viewer is DVIWIN, which can be downloaded from http://www.ph.unimelb.edu.au/~jpc/textbook/american/dviview.html which you will find a more user-friendly site than Aladdin's. DVIWIN manufactures fonts whenever it needs them, so it requires less disk space than CDVI but operates more slowly, at least at first. The screen output is a little better than CDVI's.
