Fortran 2018

Fortran 2018, ISO/IEC 1539:2018, is the current standard- an official copy can be ordered from ISO. It has two parts:

  • Part 1 - Base language
  • Part 2 - Varying length character strings (N1375 is the Final Draft, unchanged since Fortran 2003)

Previously it was called Fortran 2015. (See N2144 for discussion of the name change.)
