[1746 Japan National Activity Report (Takata)] [1748 Clarifications of Coarray Memory Model (Maclaren and Donev)] My last day in the office before going to Japan will be next Thursday. 6 Nov. If possible, please send any new papers by then. Beyond then, please use email or the J3 site. As I see it, the most difficult problems that we need to face in Tokyo are: 1. Whether coarrays should be integrated in Part 1. 2. Whether to allow coarrays to be volatile. I have a suggestion re 1, which no-one seems to like (does this mean it might be suitable as a compromise?!): follow the precedent of Fortran 77 where there was a full language and a subset language. One caught on and everyone talking of Fortran 77 now means that one. It was done with facing pages specifying the two levels, which would not be practical for Fortran 2008. I think we would need to concatenate the two, which should not a problem in these days of electronic publication. Which of the two is developed further (or neither or both) would depend on their success in the field. If it is just one, that will be what future generations will regard as Fortran 2008. My suggestion re 2 is in N1752. See you in Tokyo. John.
