WG5 Convener's report

Prepared for the BCS Fortran Specialist Group AGM, May 2001

1. Content of Fortran 2000

The main enhancements that will be in Fortran 2000 (the official name has not been chosen but WG5 uses this as a placeholder) are as follows:

	Floating point exception handling	TR 15580
	Allocatable components	TR 15581
R1	Derived type I/O	N1322
R2	Asynchronous I/O	(see N1189 item #52)
R3	Procedure pointers	(see N1189 item #43)
R4d	Control of I/O rounding	T9 in N1323
R4f	Constants for opaque types	T9 in N1323
R5	Parameterized derived types	(see N1189 item #14)
R6a	Inheritance	(see N1189 item #88 and N1272)
R6b	Polymorphism	(see N1189 item #88 and N1272)
R6c	Implicit root type	(see N1358)
R6d	WITH-like construct	(see N1364)
R7a	Constructors	(see N1355)
R7b	Destructors	(see N1189 item #89)
R8	Internationalization	N1320
R9	Interoperability with C	N1321

and all these have been incorporated in the latest draft standard, though some polishing is still in progress.

2. WG5 meeting in Oulu, August 2000

We confirmed the content of Fortran 2000 (see above) and constructed Corrigendum 1 to the Fortran 95 standard. We then went in a mode supporting J3's work. We made good progress in constructing first drafts of interpretations for J3 to consider at its next meeting. We did technical work on the items (R6 and R9 in the above list) that most needed it at that time, again for J3 to consider at its next meeting. We reviewed the current draft and suggested many minor changes. It was a productive meeting and J3 appreciated our input.

3. SC22 meeting in Nara, Japan, September 2000

This was my first meeting as WG5 convener and it was an easy one for me since there were no new projects to propose.

WG5 asked me raise the matter of junk mail coming from the SC22 site; this was very sympathetically received and the site manager promised to do something about it.

I also discussed the availability of cheap standards via the internet, following the successful Oulu downloading of the C standard for 18 dollars. SC22 resolved to participate in any trial of making inexpensive standards available.

Most of the discussion involved WG20 - internationalization - and I got landed to chair a breakout session, probably because of not being involved. I did my best in a pretty impossible situation.

4. Publications

It has been a productive year for publications.

Part 3 of the standard (conditional compilation) was reprinted in late 2000 because a line of normative text was omitted.

Revised versions of the two TRs are about to appear. The revisions were needed because of problems found when the ideas were integrated into the draft standard.

Corrigendum 1 is about to appear.

5. WG5 meeting in London, July 30 to August 3

Much work will be needed on the interpretations and to generate Corrigendum 2. We will review the content of the new standard and we will review the current draft. As in Oulu, I see the main role to be supporting J3's work.

6. Timetable

The current timetable is as follows:

J3 delivers to WG5 edits for draft corrigendum 2	2001-06
J3 delivers to WG5 current working draft	2001-06
WG5 constructs corrigendum 2	2001-08
WG5 provides J3 with review of F2000 working draft	2001-08
Corrigendum 2 submitted for processing	2001-10
J3 delivers proposed CD to WG5	2002-06
WG5 approval of CD	2002-08
First CD submitted for registration and approval	2002-09
First CD ballot initiated	2002-10
First CD ballot comments available	2003-02
WG5 meeting to resolve comments	2003-04
J3 delivers final CD to WG5	2003-06
WG5 review meeting	2003-08
Final CD submitted for approval	2003-09
Final CD ballot initiated	2003-10
Final CD ballot comments available	2004-03
WG5 approval of draft DIS	2004-04
DIS registered	2004-06
DIS ballot initiated	2004-07
DIS ballot results available	2004-10
Standard published	2004-12

My immediate concern is with corrigendum 2. It will be hard to get this done by August. There are a lot of outstanding interpretations.
