Hey Justin, Use the manual pages. My gfortran is installed in a library /gcc-4.1 The manual is obtainable by: > man -M/gcc-4.1/man gfortran It might be, if your gfortran is bundled with your system, that > man gfortran will do it. Otherwise do a search: I found http://www.die.net/doc/linux/man/man1/gfortran.1.html using Google, at #3 amongst 46,600 hits. Paul T
