5. Reports
5.1 SC22 Matters (Convenor)
- John Reid will attend the SC22 meeting in Nara, Japan next month.
- The SC22 Secretariat has had considerable turnover in personnel since the
last SC22 meeting, but is functioning despite the lack of continuity.
- John will present a paper (see N1384) requesting that SC22 documents in
Word format be avoided.
- Japan discovered a line missing from the published version of Part 3 of
the Fortran standard and ISO has agreed to reprint it.
- The WG5 web site has been moved to NAG. Gratitude was expressed to NAG
for making the facility available and to Ian Hounam for his assistance.
- John will discuss with SC22 the need for filtering unwanted email from the
SC22 email reflector system.
5.2 National Activity Reports (Heads of Delegations)
US Keith Bierman (N1388)
Sweden Lars Mossberg
UK David Muxworthy (N1398)
Finland Petri Mahonen
Netherlands Matthijs Van Waveren (N1394)
Japan Makki Takata (N1386)
From countries not present:
Russia N1396
France N1385
The Convenor will send replies to Russia and France.
5.3 Report from Primary Development Body (NCITS/J3 Chair)
N1389 was presented by Larry Meadows. The major problems are R7 -
Generalized Constructors/Destructors and R9 - Interoperability with C.
It
is believed J3 can get the work done. WG5 will establish subgroups to
investigate how WG5 can help in these areas. The Convenor would like a
document from this meeting detailing the final WG5 requirements for
Fortran
2000 - a revision of N1382.
5.4 Reports from other Development Bodies (Editors/Heads)
TR15881 - Malcolm Cohen: No activity at this time
TR15880 - John Reid: There are some unresolved issues in Section 15
of the draft standard. A WG5 Subgroup can look into these.
Part 2 - John Reid: No activity at this time
5.5 Liaison Reports
None
5.6 SubGroup Organization:
Interpretations: Reid, J., Muxworthy, Reid, N., Meadows,
Cohen
Review of F2000 draft: Snyder, Mossberg, Takata, Martin
Interoperability: Van Waveren, Meadows, Morgan, Bierman
Data Issues: Cohen, Morgan, Snyder
Coco Corrigendum Takata, Reid, J.
5.7 Presentation on N1355 and three possibilities of action (Cohen)
The three possibilities are 1) the simple solution, 2) a complex
solution
(proposed by K. Hirchert at J3 meeting 153), and 3) drop the
requirement.
Concensus was to proceed with the simple solution proposed at the
Cadarache
meeting.
Tuesday, August 15 0900 - 1745
6. Subgroup Recommendations
6.1 Interpretations (N1404)
The Interpretations Subgroup recommended that three interpretations from WG5
ballots be returned to J3. They are 067: Writing zeros; 068: Asterisks as
I/O
units; and 071: Character Array Constructors. Edits were recommended for
070:
Asymmetry between constant specification and initialization expression; 077:
INTENT (IN) Dummy arguments and NULLIFY. The other interpretations balloted
were
accepted without modifications.
Interpretation 021: Restrictions on <generic-spec> on END INTERFACE was
discussed. A straw vote was taken: Should Example 1 be standard conforming?
(4-
7-4) No recommendation was made.
6.2 Interoperability (N1402)
The Subgroup reviewed 3 unresolved issues.
A straw vote was taken on restoring the rounding mode across C function
calls.
The vote was 4 to keep the current restriction; 7 to relax the restriction;
4
undecided. A question arose on whether EXTERNAL procedures defined by means
other than Fortran should be treated differently from procedures with the
BIND(C) attribute.
Two straw votes were taken regarding pointer inquiry: Should C pointers be
tested against NULL only (1), tested for pointer equality as well (13), or
undecided (1)? Should the mechanism for testing be an intrinsic procedure
(14),
overloading of .EQ. (0), or undecided (1)?
The third issue involved adding special kind type parameters. Should many
be
added (0), only one - C_SIZE_T corresponding to type size_t in C (11), none
(0),
or undecided (4)?
Wednesday, August 16 0900 - 1745
7. Subgroup Recommendations
7.1 Interpretations (N1410)
These suggestions will be offered to J3 as input to their Fortran
95
maintenance activity.
7.2 Data Issues (N1407)
N1407 provides suggested edits to fulfill the generalized
constructors
part of requirement R7. Additional lines will be added to the
second
example in Item 4 to show the use of the constructors.
7.3 Interoperability (N1406)
N1406 addressed the question raised regarding a distinction
between
procedures with the EXTERNAL attribute and procedures with the
BIND(C)
attribute. It was argued that the recommended approach would nail
down an existing portability problem rather than introduce a
change to
the language. This approach was approved unanimously by straw
vote.
7.4 Coco Corrigendum (N1409)
A draft corrigendum will be balloted after this meeting. All of
the
Japanese concerns in N1387 and the Russian comments in N1397 were
addressed.
Thursday, August 17 0900 - 1745
8. Subgroup Recommendations
8.1 Review of Fortran 2000 draft (N1405, N1408)
The results of the Review Subgroup were discussed. A few items were deleted
from the cited papers. The Convenor will concatenate the remaining items
and
forward the suggestions to J3 in a single document.
8.2 Interpretations (N1411, N1414)
The cited documents were discussed. Some changes were accepted. The
Convenor
will concatenate all reviewed interpretations in a consistent format to
forward
as input to the primary development body's Fortran 95 maintenance activity.
8.3 Data Issues (N1417)
Malcolm Cohen presented suggested specifications and syntax for destructors
(requirement R7). A question was asked about the possibility of allowing a
final procedure to have the BIND(C) attribute. Offhand it would appear to
present too many difficulties and lead to more unresolved issues for
interoperability with C.
9. Administrative Items
9.1 Draft Resolutions (N1412)
The first draft of the Oulu Resolutions was presented by David
Muxworthy. There was some question about the agreed informal name of
the next standard and a straw vote was taken. Should the name be:
Fortran 2000 9
Fortran 200x 2
Undecided 4
We will stay with Fortran 2000.
9.2 Content of Fortran 2000 (N1413)
Requirements from the Cadarache meeting will be added to the final version
of
N1413.
9.3 WG5 Business Plan and Convenor's Report (N1415)
Comments will be added about the email problem. A few other minor changes
were
accepted by the convenor.
Friday, August 18 0900 - 1300
10. Document Review
The resolutions and other documents (N1403, N1411, N1413, N1415, N1416)
were
reviewed for accuracy and completeness.
11. Additional Interpretations (N1404)
No objections were raised.
12. Summary of the changes from Fortran 95
This is deferred to the future.
13. Closing Business
13.1 Future meetings
2001 BSI Headquarters, London 30 July - 3 August
2002 somewhere in The Netherlands ?-? August
13.2 Any other business
Thanks were expressed to the hosts for the meeting arrangements.
The Convenor is requested to convey WG5's wishes for a speedy
recovery
to Lawrie Schonfelder.
14. Adoption of Resolutions
The resolutions were approved by all six countries in attendance and the
unanimous consent of individual members.
15. Adjournment
The meeting was adjourned at 10:10 AM, August 18, 2000.
