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? George Planansky email: gplan@ra.umb.edu Atmosphere Environment Research Cambridge, MA 02139 (617) 547-6207
