2.6 Approval of the Minutes of the Oulu Meeting [N1418]

   The Minutes of the Oulu meeting (N1418) were adopted unanimously.

3. Matters arising from the minutes

   Future meetings: The next WG5 meeting will be in Las Vegas. It will be a
   5 1/2 day meeting together with J3 in August 11-16, 2002.
   Wolfgang volunteered to host a meeting in Dresden in 2003.
   The convener pointed out that a joint WG5/R3 meeting is needed in April
2003. 
   Dates March 30 through April 4 seemed preferable for most delegates.

4. Status of Oulu Resolutions [N1412]

   O2: The question on unauthorized and irrelevant use of the SC22 e-mail

problem.

5. Reports

   The convener reported from the SC22 meeting in Nara, Japan in 2000:
   Input from WG5 was essentially the e-mail complaint.
   The big issue at the meeting was Internationalisation.
   The SC22 secretariat is now distributing almost all Word documents 
   as PDF files.

6. Subgroup Recommendations

   6.1 Fortran 2000 (N1453)

   Interpretation     David Niki Mathijs John

   The convener instructed the members to study Technical Corrigendum 2
   (N1445) for correctness.

   The convener instructed the members to study WG5 Business Plan and
   convener's Report to the SC22 Plenary (N1448).

 




                Wednesday, August 1   0900 - 1745

7. WG5 Business Plan (N1438)

   The business plan was reviewed with some additions and modifications, for
   example a work item of Van Snyder's TR on submodules and updated dates
for 
   future meetings. A new version of N1438 will be written by the Convener.


8. Dan Nagle on the future Fortran standard.

   My suggested strategy is to put together a number of small work items.
   This is also in conformance with the strategy that the next standard be a

   minor revision. The small work items should preferable be orthogonal so 
   that they will be finished independently and in a short time period.
   Examples: take good ideas that have been cancelled by J3 due to lack of
   time. Implement "industry standard" features. Use common parts.
   Build on Fortran's clarity, ease of use, portability.
   It was pointed out that we have to go through the process that
requirements
   be collected from the countries but there is nothing to stop us "hinting
   where we want to go".
   Dan's proposal on the next standard was well received and a paper (N1460)
   outlining it will be written.
   It was also pointed out that promotion of Fortran is important.

9. New features of Fortran 2000.

   It was decided that a summary on the new features on Fortran 2000 will
   also be made by Dan in paper N1459.

   An article on the new features in Fortran 2000 by Dan will shortly
   appear in "Dr. Dobb's Journal".


10. Subgroup Recommendations

  10.1 Fortran 2000: N1453
     A straw vote on the items was taken. The question was: Do we keep this
     item and transfer it to J3?

     Straw vote: Item 1: 7Y 0N 4U (Y = Yes, N = No, U = Undecided)
                 Item 2: 1Y 4N 6U
                 Item 3: 7Y 0N 4U
                 Item 4: 4Y 1N 6U
                 Item 5: 3Y 4N 4U
                 Item 6: 0Y 2N 9U

      Result: Keep items 1,3,4. Make a new paper with these 3 items and
leave
              item 5 in with a lower priority.


  10.2 Interpretations

        Papers N1451, N1452, N1456, N1457, N1463 were presented and will be 
        discussed Thursday morning.

        It was recommended that N1458 be studied. It concerns an MTE on the
        PROTECTED attribute.

        Straw vote derived from interpretation 17.
        Is the wording in 12.2.2, third sentence, ambiguous?
        Result: 6Y 4N 1U.

  10.3 Fortran 2000

        N1461 concerning IEEE was presented. It will be discussed Thursday 
        morning.
        N1462: Interoperability with C. Needs to be more elaborate. Ready 
        tomorrow.


                 Thursday, August 2   0900 - 1745

11. Subgroup Recommendations

         Should we reject interpretation 91? 
         6Y 0N 3U

    11.2 Interpretations (N1456)
         Delete 00000e.
	 Van suggested three small edits that were accepted by WG5.
	 They will be included in the final version.

         Straw vote: Accept Interpretation 8 as is (with Van's additions)?
         1Y 4N 4U

	 Strike interpretation 206 from document. If time to work on
	 it, bring it back.
         Delete 208, 210 from document.

         Small change in JP-04 suggested by Malcolm and accepted by WG5.
         Strike JP-24. Bring back later if possible.

    11.3 Interpretations (N1463)
           Interpretation 9 was deleted since it had already been covered.
           Interpretation 17 was deleted due to highly diverse opinions in
the 
           group.

	   Re JP-05: No, the requirement should be a constraint in
		     Fortran 2000, but remain a simple requirement in
		     Fortran 95.

           Re JP-17: Deleted.
 
           Re JP-31: Put back.

    11.4 Interpretations (N1457)

           WG5 passes all interpretations in the document.

    11.5 Interpretations (N1452)

           Malcolm makes a new document on JP-17. 

    11.6 Fortran 2000 (N1453)

           A new version of N1453 was discussed. Typo needs to be corrected.
           Otherwise passed.
 
 
   11.7 Fortran 2000 (N1454)

          Item 1: To be reworded by Van.
          Item 2: Deleted.
          Item 3 (Named Scratch files):
          Straw vote: Are named scratch files desirable?
          0 De  10 UDe  0 Un (De = Desirable, UDe = Undesirable, Ud =
Undecided)

            Van changes wording on scratch files accordingly.

          Item 1: ok (small typo to be fixed).
          Item 2: Phrase more generally (relating ASCII and ISO 10646).
          Item 3: Straw vote: Delete item 3 from document?

         The PROTECED attribute. Paper N1458.

           Presented by Malcolm.
           The idea was very favorably received and the advised action was
"put
           it in the standard as long as it does not has any impact on the
time 
           schedule".
