| <p>The GNU Fortran compiler implements |
| ISO/IEC 1539:1997 (Fortran 95). As such, it can also compile essentially all |
| standard-compliant Fortran 90 and Fortran 77 programs. It also supports |
| the ISO/IEC TR-15581 enhancements to allocatable arrays. |
| |
| <p>In the future, the GNU Fortran compiler will also support ISO/IEC |
| 1539-1:2004 (Fortran 2003), ISO/IEC 1539-1:2010 (Fortran 2008) and |
| future Fortran standards. Partial support of the Fortran 2003 and |
| Fortran 2008 standard is already provided; the current status of the |
| support is reported in the <a href="Fortran-2003-status.html#Fortran-2003-status">Fortran 2003 status</a> and |
| <a href="Fortran-2008-status.html#Fortran-2008-status">Fortran 2008 status</a> sections of the documentation. |
| |
| <p>Additionally, the GNU Fortran compilers supports the OpenMP specification |
| (version 3.1, <a href="http://openmp.org/wp/openmp-specifications/">http://openmp.org/wp/openmp-specifications/</a>). |
