As used in the F90 standard, the term "processor" has a very specific meaning. It does not refer simply to the hardware on which the user's program is to be compiled and run, but to the entire computing system, including hardware, operating system, compiler, libraries and runtime system. Thus, the fact that virtually all hardware these days supports mixed case is irrelevant. A compiler vendor could still, in principal at least, simply prohibit lower case characters. The vendor would, of course, find it very difficult to _sell_ such a compiler. > >Any other comments from the WG5 ???? > Bernard >PICHON > -- Leonard J.
