N1844 Result of WG5 informal ballot on the schedule and draft of TR 29113 (Reid)

17 November 2010

Fortran 2008 published

Fortran 2008 was published on 6 October as ISO/IEC 1539-1:2010, price CHF 338.

TR on further interoperability with C

J3 made good progress with the draft Technical Report on further interoperability with C and the result, N1838, is currently the subject of an informal WG5 ballot, see N1843, which has a deadline of 9 a.m. UK time on 7 December. Anyone is welcome to read N1838 and comment in the ballot.

Fortran 2008

The FDIS has been approved 18-0-15, see N1836. We can expect publication by November.

TR on further interoperability with C

WG5 activity in the next few months will be focussed on the TR on further interoperability with C, see the strategic plans in N1812. At the SC22 plenary, the convenor asked for a year's extension for this since without an extension the slightest slippage would lead to cancellation of the work item. No further extension is permissible, so WG5 must keep to its schedule.

TR on Further Coarray Features

In 2008, WG5 declared "that the content of the Technical Report on Enhanced Coarray Facilities in Fortran is as shown in document J3/08-131r1", that is, would contain those coarray features that were deleted from Fortran 2008 at that time. However, it would be foolish not to consider alternatives. The convenor has therefore started discussion with a paper on requirements, N1835. It is expected that WG5 will decide on the technical content of the TR at its meeting in June 2011.

Part 3 of the Fortran Standard

Part 3 of the Fortran Standard has been confirmed following its systematic review, see N1832, part 1 and N1832, part 2. Although no formal resolution has been made by WG5 on this, discussions have been in favour of withdrawal since there has only ever been one implementation. The convenor therefore asked SC22 at its September plenary to request a JTC1 country ballot for withdrawal.

TR on Enhanced Module Facilities

The TR on Enhanced Module Facilities has been confirmed following its systematic review, see N1833, part 1 and N1833, part 2. Since its features are incorporated in Fortran 2008, this will become redundant once the new Standard is published. The convenor therefore asked SC22 at its September plenary to request a JTC1 country ballot for withdrawal once the new Standard is published.

Revision of the FDIS for Fortran 2008

The ISO Secretariat has requested some very minor changes to the Final Draft International Standard (FDIS) for Fortran 2008. The new version is N1830 and will be forwarded today. Details of the changes are in N1831. David Muxworthy has provided three more pdf files pertaining to meetings in the 1980s. They are N025, N030, and N075.

Van Snyder has prompted me to copy electronic copies of the Fortran 66 standard, the Fortran 77 standard, and the Military Standard 1753, which went with the Fortran 77 standard, to this web site. [Fortran Standards > Earlier Standards]

The FDIS for Fortran 2008 is ready

The Final Draft international Standard (FDIS) for Fortran 2008, N1826, is ready and will be sent to SC22 today. The Editor, Malcolm Cohen, made a draft, N1814, that included all the edits agreed at the meeting in February. This was checked by the whole of WG5 in an informal ballot, see N1825. A small number of very minor changes were suggested in the ballot or found subsequently. Details of these further changes are in N1827 and have been checked by John Reid, Dan Nagle, and Van Snyder. Meanwhile, David Muxworthy has produced a corrigendum for Fortran 2003, N1823, that contains all the edits in Corrigenda 1 to 5. While this in not an official document, it has been checked by John Reid and Stan Whitlock.

Also, John Reid has revised his unofficial summary of the coarray features, see N1824.

Finalization of Fortran 2008

The main business of the WG5 meeting in las Vegas, 15-19 February, was to review the comments from the SC22 ballot on the FCD draft of Fortran 2008, see N1802. to decide on changes and to prepare the Disposition of Comments document. Edits to the FCD were made to respond to all the comments except three from the UK (see below). The final WG5 ballot on interpretations to Fortran 2003 was concluded just before the start of the meeting. All the comments were processed and corresponding edits to Fortran 2008 were made, as appropriate. A final corrigendum was prepared, which will be placed on the WG5 site soon. Further interpretation processing will be against Fortran 2008.

All the edits agreed will need to be made to the draft and checked. The ISO procedures allow no further editorial or technical changes so the standard is essentially complete. It is hoped that it will be published in August.

Three comments from the UK

There were three comments from the UK that were not accepted by WG5. The first proposed a new project to define a compatible subset; here, opinion was divided but a majority of WG5 was opposed, mainly because progress is being made by vendors towards full implementation of Fortran 2003 and the construction of a subset would discourage this. The second proposed that coarrays be developed separately as an optional feature; this had already been discussed extensively by WG5, so was not discussed further. The third identified a defect re the arithmetic IF statement and suggested deleting it; WG5 was sympathetic to the idea of deletion, but felt that the change was not necessary and corrected the defect since this involved fewer changes.

TR on Further Interoperability with C

Work on the new standard was largely completed by Wednesday morning of the WG5 meeting, which made time available to give attention to the draft TR on Further Interoperability with C, N1808, and prepare a paper on the objectives, see N1820. It was decided that the development body should be PL22.3 (J3), that a new email list for the work be set up, and that the schedule be delayed by 8 months to allow two meetings of PL22.3 to work on the details before submitting a DTR to SC22. It is hoped that the TR will be published by November 2011.

TR on Further Coarray Features

Work has not yet started on the TR on further coarray features. It was decided that this work should follow one year behind with the aim of publication in November 2012.

Further revision of Fortran

Further revision of Fortran WG5 confirmed its decision at the previous meeting not to start consideration of plans for the revision of Fortran 2008 before June 2012.

Result of the DTR ballot on Fortran 2008

The result of the ballot on the SC22 site has a document that was not on the UK version, which was used for the message of 18 January. An HTML version is visible as N1804 and says "This FCD has been approved. WG 5 is instructed to take the comments into consideration, prepare a disposition of comments text and provide a revised text for FDIS ballot."

Result of the DTR ballot on Fortran 2008

The result of the DTR ballot on Fortran 2008 is 12-1-6. Details are in N1801. The UK voted "no" and three "yes" votes (USA, Japan, Canada) were accompanied by comments. The reasons for the UK "no" vote, together with the comments of USA, Japan, Canada and further comments from the UK, are contained in N1802. The US comments refer to documents on the J3 web site and the UK comments refer to N1803. In addition, editorial comments have been provided by the ISO Secretariat, see N1798. The comments in all these documents will be considered at the forthcoming WG5 meeting in Las Vegas, February 15-19.
