%%% File: Fortran.TeX
% This is a file of commands for printing out programs using TeX
%                               -- see DIRTY TRICKS in TeXbook
%
%       This version is designed to print source code at 9 point
%       fitting an 80 column line into a 6 true inch width with
%       8 point line numbers before each line.
%       It handles TAB (^I) characters almost the same as DEC
%
%       usage:
%               \input fortran          % put this early in the file
%               \listing{file.ext}      % use dev:[dir] if you wish
%
