     Just to clarify a "fine" point, in ANSI FORTRAN '77, the construct

                             DOALLI=1,N

(spaces are null in FORTRAN) is defined to mean

                           DO ALLI = 1, N

(spaces are still null, but I hope my meaning is clear).  Therefore, the
so-called DOALL extension has changed the semantics of standard FORTRAN,
rather than extending the language.  The shuttle people might have a right
to be peeved, but they shouldn't direct their displeasure at the CM FORTRAN
implementors.

[I agree, adding ambiguous syntax that can change the meaning of an existing
legal program is not good language design.  The entire issue of parallel
extensions to Fortran and to C is a hot topic -- I get lots of interesting
mailings from the Numerical C Extensions Group. -John]
