Regarding Sun's F77  (on a Sun 3, running 4.03), will it do unformatted
read, write on stdin, stdout?  The Sun manual says you can use
"form='unformatted'" in an open statement, to change the attribute of a
file that is already open.

I can't find an assertion that rules this out for units 5 and 6.  The
compiler accepts an "open(unit=5,form='unformatted')" statement, but it
bombs at runtime.

There is an io init library routine (in Fortran) which opens 5 and 6. Can
I use this to enable unformatted read, write?

I'm using the alternative of C subroutines, but it'd be a lot cleaner to
stick to Fortran.  Useful as it would be, surely Sun's Fortran will do it,
right?
