The GNU Fortran compiler is a front end for gcc, the GNU C compiler. It used to be called f77 and is now called gfortran: I don't know when the name changed. Under RedHat Fedora 14 the fortran compiler package is called gcc-gfortran. Its installed by default in Fedora 14, so 'man gfortran' tells about using the compiler and running 'gfortran --help' displays its help message. If you don't have gfortran installed, try searching for a gcc-gfortran or gfortran packageto install. If that doesn't help, ask on your distro's forum. > There is a file > > Code: > /usr/share/man/man3/ExtUtils::F77.3pm.gz > GIYF. In this case Google told me that ExtUtils::F77 is not a compiler: it is a Perl module that helps a developer to work out how to link C programs with Fortran subroutines. Martin
