I recently asked my professor if he had any research opportunities in the following semesters and he told me that I should download and play around with 'Fortran G77 Compiler' and get back to him. So, I've looked into it but didn't make much progress.First off, I'm confused with which program he is specifically talking about.. I noticed there are several different versions of Fortran say, GNU Fortran, Fortran 90, 95, etc... Not really sure. But I think he wants me to use specifically Fortran G77 Compiler.. I'm using a Windows7 computer [I'm not against downloading a different OS, I just wouldn't know how to go about it]. So basically I'm asking, where can I download this, or what am I looking for exactly? Do I need to download Fortran, and then a Gfortran package or something? Or is a Fortran G77 Compiler just one download? Do I need an editor or can I use notepad or MSDOS Windows, if so how? Are there any tutorials on how to use/download Fortran G77 Compiler on Windows? Thanks.
