I'm kind of on the fence about it. The point of hiding __sF is to remove all dependencies on the size of the FILE structure from applications, and that's a very worthwhile thing to do. Modula-3 is a special case (and a pathological one), and it shouldn't influence the decision too much. I don't think there's a way to fix it entirely in the OS without re-establishing the dependency on the size of FILE. We are lucky that ezm3 just happens to work. The PM3 port can be fixed with a 5.0-specific patch or two, but ... not today. John -- John Polstra John D. Polstra & Co., Inc.
