Files of extension .f90 or .F90 should automatically enter f90-mode when visited in XEmacs, when fortran package is installed. try M-x locate-library RET f90 RET to see whether the file is installed and can be found. This bit of lisp should return your installed version (package-get-info 'fortran-modes 'version) which should be "1.05" Best regards, Adrian -- Adrian Aichner mailto:adrian＠xemacs.org http://www.xemacs.org/
