I think the key issue here is that there is no compiler in use anymore that *only* supports F77 syntax (even those that have "77" in their executable name). There hasn't been a only-supports-fortran-77-syntax compiler for many, many years (since the early-/mid-90s? That's a guess). That doesn't matter, if it's not in the F77 standard then we can't have it in the F77 bindings.

There are no F77 bindings. There are only implicit Fortran bindings in mpif.h.

So using (KIND=foo) syntax, even though that didn't debut until F90 or F95 (or whatever; I'm no Fortran expert) is perfectly acceptable here. Not without renaming the bindings (I suppose that would require some wording changes that I'm not totally opposed to).

We already have some KIND types in the MPI Fortran bindings (MPI_AINT_KIND is my favorite :-) ). -- Jeff Squyres [email protected]
