Welcome to the BCS Fortran Specialist Group Website

June 2024

The Group was established in 1970 to provide an open forum for Fortran users.

Its main aims are:

  • to disseminate information about Fortran and its application in various fields,
  • to provide a platform for discussion of users' needs and requirements in future versions of Fortran,
  • to encourage the development of the language in collaboration with national and international standardization bodies,
  • to promote the use of the Fortran language.

To discover more about the Group and its activities please explore the links on the sidebar of this page.

At the UK RSE conference (RSECon23) there were a couple of sessions that were relevant to Fortran. The first was a discussion on Fortran training. The notes from that session are available here althugh unfortunately without the audience contributions. The second was a talk by Sean Marshallsay of Queen's University Belfast covering refactoring Legacy codes to remove global state.

[07/18] Fortran Standards status

Following the June WG5 meeting in Berkeley, CA, the Final Draft International Standard (N2159) was constructed for ballot. It is expected that the ballot will close in October and if no further issues are found, the F2018 standard should be finally published by ISO in November.

The minutes from this meeting (N2158). and the strategic plan (N2154), can be found on the wg5-fortran.org site.

[05/18] Fortran Standards status

The Fortran 2018 standard is nearly complete. The formal voting period for the DIS (Draft International Standard) is over and J3 will be responding to the country comments and constructing a new draft at its meeting in Berkeley, California, 11-15 June. It is expected that the changes will be minor and that the standard will be published later this year.

[05/18] J3 Meeting Report

The FEB-2018 J3 meeting was mainly concerned with analysing the results of the WG5 user survey, N2147, and choosing the list of features to recommend to WG5 for inclusion in Fortran 202X. The full record of the meeting can be found on the J3 site (https://j3-fortran.org). The survey results showed that two features:

1. generic programming or templates and
2. exceptions

were very popular with the users. Therefore J3 decided to recommend to WG5 to add these to Fortran 202X. The J3 members present then made further suggestions, partly based on the survey and partly on their own views on the next Fortran standard. These are documented in J3 documents
18-122r1 and
Among these are: bit stings, better enumeration types, asyncronous subroutine execution, degree trig functions, protected structure components, short-circuit logical operations, more character intrinsics, constants for logical kinds, binary compatibility of C descriptors, etc. The next step is for WG5 to agree the exact list of features for Fortran 202X at the JUN-2018 meeting ( N2148, N2150 available from https://wg5-fortran.org).

[11/17] Fortran Birds of A Feather session at SC17

Members of the FSG were instrumental in proposing a 'BOF' session at the premier High Performance Computing Conference SC17 as a way to mark the 60th Anniversary of Fortran

The BOF Fortran Is 60 Years Old - Has It Changed for the Better? took the form of short presentations by industry experts followed by a lively discussion. In particular the audience (many under 30!) was interested in how the committee decided on features to add to the language and made requests for a template feature.
