We also use a lot of C routines for I/O within a mostly-fortran
framework!  Particularly because this can speed up I/O from 50%
to 2000% (NOT a misprint - 20 times!) on Unix, OS/2, and Apollo;
apparently the Fortran I/O model mismatches these machines and/or
is too general for efficiency, while with C we can special-case
optimize what we really need, and FLY.  You have my full support!!!
