Wagener" To: sc22wg5@dkuug.dk Subject: informal JLW report on the Feb'1997 joint WG5/X3J3 meeting Content-Type: Text/Plain; charset=US-ASCII Content-Disposition: Inline The principal objectives of this joint meeting were to (a) complete the identification of requirements for the technical content of Fortran 2000 and (b) advance the technical development of these requirements. Object (a) was fully met; as for objective (b), most of the technical work involved the pre-existing requirements rather than the new ones. Regarding objective (a), the three technical reports (floating point exception handling, allocatable components, and C interoperability) were confirmed as Fortran 200 requirments, as were the other five previously identified requirements (derived-type I/O, asynchronous I/O, procedure pointers, interval arithmetic, and parameterized derived types). Three new requirments were added: (1) object-oriented inheritance and polymorphism (paper 97-131), (2) constructors/destructors, and (3) internationalization of character sets and display formats. The MTE (minor technical enhancement) category was reaffirmed, with WG5 reviewing the specific list of MTEs at each of its meetings. At this meeting 5 (of the 17) MTEs were removed (M.8, M.9, M.12, M.13, M.14 - see paper 97- 010) and seven additional items were identified as MTE candidates (see 97- 010r1). Regarding objective (b), the final syntax for parameterized derived types was approved, as were the specs for M.16. Tutorials/discussions/straw-votes took place regarding procedure pointers, asynchronous I/O, interval arithmetic, and internationalization. An evening meeting of the development body for the technical report on C interoperability resulted in some changes to that report; a pdTR ballot is scheduled later this spring. An evening meeting of the development body for conditional compilation revealed continuing lack of consensus, though a slight preference for the Fortran-like CoCo over the fpp/cpp version. Accordingly, WG5 will conduct a letter ballot relative to continuing this project; if the ballot results indicate continuing, the Fortran-like CoCo will be processed as Part 3 of the Fortran standard. Because of the additional requirements, the schedule for Fortran 2000 was slipped one year. The new schedule calls for X3J3 to deliver the first draft to WG5 in early 2000 (rather than early 1999), for eventual publication as a standard in late 2002 (rather than late 2001). The papers referenced above may be obtained by FTP from ftp.ncsa.uiuc.edu/ x3j3. The next X3J3 meeting is May 12-16 in Las Vegas, and the next WG5 meeting is July 21-25 in Vienna; there is no future joint WG5/X3J3 meeting scheduled. Jerry Wagener
