I have no idea how you arrived at that conclusion.  Fortran 8X is
specifically designed to be upward compatible with FORTRAN 77, and I have
seen nothing posted in this newsgroup that would imply otherwise.  

It is true that a great many programs will not work with a Fortran 8X
compiler, but these are programs that do not even conform to the existing
77 standard and are likely to break anyway as soon as they are moved to a
compiler other than the one that was used for the original program
development.

There is no guarantee that future versions of Fortran (F9X and beyond) will
still be compatible with FORTRAN 77, but at least there is fair warning as
to where the differences are likely to be.
