      the Internet Archive
    A selection of open source or free Fortran compilers and tools
      
         - GNU gfortran - Fortran 95 + most of 
             Fortran 2003 and 2008 and some of the proposed Fortran 2015 features
- GNU g77 - 
             Fortran 77 - no longer being developed
- g95 (Internet Archive capture) - branch from gfortran - Fortran 95 + 
             many Fortran 2003 features
- F (Internet Archive capture) - a highly regular subset 
             of Fortran 95 - good introduction to modern Fortran. Note that the character F was used as the logo for this compiler, possibly a fact unknown to those who use it more recently to stand for Fortran in general.
- Minimalist GNU for Windows (MinGW, Internet Archive capture) - 
             package to enable above compilers to run under Microsoft Windows
 This project appears to be continuing at https://www.mingw-w64.org/.
- DISLIN - high-level Fortran-callable 
             plotting library for displaying data as curves, graphs, charts, plots, 
             surfaces and maps
- Some commercial compilers are available free of charge for non-commercial use, 
             some are 
             listed here 
             and others can be found in the links below
A selection of suppliers of commercial Fortran compilers, libraries and tools
      
      A selection of providers of Fortran training and consultancy
      
      A selection of other Fortran online resources - some overlap is likely
