A free for some uses Fortran 90 compiler can be found somewhere under http://www.psrv.com/ although I hear tell that the license is very restrictive about what you can do, and ISTR hearing it's quite buggy. I've got a feeling its implemented as a translator to F77. If you don't mind using a subset compiler, then F provides the nice bits of Fortran 90, and there is a no-cost version avalible for download. The URL is something like http://www.imagine1.com/ Other than that, there are several commercial offerings. I've not had any real problems with the Portland Group compilers but haven't tried anything else. I don't know how much luck you'll have finding a translator, either - those that exist tend to convert F77 to F90. There is a comprehensive Fortran on Linux web page out there, but I don't seem to have the URL handy.
