Absoft The premier multiplatform compiler people (PC, Mac, Linux, 64-bit, etc.), your only source for Mac Fortran. The Windows Pro Fortran User's Guide for Windows version 14.0.2 is missing Appendix D, AWE RGB Colors, which lists 139 RGB colors that are accessed by variable names such as AWE_spring_green. The Mac and Linux manuals do have Appendix D. AWE is the Absoft Windowed Environment, which maps stdout, stdin, and stderr to a text window, and in recent versions includes utilities for text boxes, alert boxes, dialogue boxes, and plots including bar plots, pie charts, and X-Y plots. The colors are for use in AWE plots. The plot utilities always have defaults, but you can use the colors defined in Appendix D, or define your own RGB colors as 32-bit integers, as in z'00FF7F', the RGB code for AWE_spring_green. The Windows Appendix D, AWE RGB Colors, is, with permission from Absoft,here.
G95 A fork of the GNU Fortran 95 project, with most if not all Fortran 2003/2008 features including a mature implementation of co-arrays, suitable for use with multiple processors on clusters. This may be the most evolved Fortran 95 compiler available, and is quite bug-free.† The F compiler is now implemented through the option "-std=F" in g95. The mingw and cygwin builds are not currently available, but builds are available for most Linux distributions (Intel, Power PC, debian, IA64, Alpha, x86_64/EMT64 - my personal favorite that I run under Fedora), Mac OS/X (both Power PC and Intel), Solaris, HP-UX 11, Solaris x86, Irix x86, and AIX Power PC. If you want it for Windows or another environment not specified here, you can try compiling it from source code. Since its back end is from a gcc C or assembly compiler, new ports do not require development of a back end so long as gcc is available for the object platform. From the home page, click "-> Downloads" then "-> Source" to get a selection of versions, including the most recent enhancement or bug-fix, or "stable" numbered releases dated October 2012 and earlier. GNU makefiles and the manual are included with the source code.
gfortran is now part of gcc, the native Linux compiler suite and available through mingw, cygwin,and directly for Windows and other environments as well as Linux 32-bit and 64-bit through Sourceforge. Note that this compiler now the full set of Fortran 95 capabilities, but with some remnants of a bug that issues warning when tabs are used to line up marginal comments on continuation lines, particularly I/O format statements.
The F Programming Language is a minimal subset of Fortran 95 that is intended for use in introductory courses in structured programming or Fortran 95/2003/2008. It is currently supported as the -std=F option by g95.
Salford Another old timer, has become silverfrost, the name of their host organization. They now offer a Fortran 95 compiler for Windows and .NET.
The Fortran Company sells compilers by others, and offers tutorials, books, and other materials on F, Fortran 95/2003/2008 for nominal cost on CDROM or on hard copy.† They offer a companion tutorial and reference book for F for a nominal cost.† I recommend F to get started, or to learn Fortran 95 if you know FORTRAN 77, C/C++ or another language but not Fortran 95.
