If you then click on OK you can proceeed. The teletype font works fine. This Web-reader works fine in both version 2.01 and 2.1. This works fine. Main page, with links to all other pages is f77to90.html.
Pictures are in the subdirectory gifs and source code in the subdirectory code.
All other document names are self explanatory, except fortran.html, which includes external links to other Fortran documents. My proposal for a directory name is f77to90. On your computer you put the file f77to90.zip on the directory where you wish the subdirectory f77to90 to be created. You then get the files installed on one directory with the HTML-files, one subdirectory gifs with pictures and one subdirectory code with the source code. When installing on a UNIX computer you are supposed to change the file name to f77to90.tar.
