    Hi.  I'm not sure if this is the right place to post this, but someone
here can probably help.

    We have a C program that writes out a file using the write() command.
Of course, VAX C creates a STREAM_LF type file instead of a binary file
like it would in UNIX.  Then a FORTRAN program has to read it in and
write it to tape.  We can do it, unfortunately it is a little cumbersome
on both sides.  The C program has to write out fixed size blocks for the
FORTRAN program to read it.  The FORTRAN program uses QIO to read in the
file, but has to keep track of what disk block it is on for the QIO to
work.  It works OK for now, but we would like a more intuitive way.

    Is there any way to write a file in C that is not a STREAM_LF
type file, or is there a way to open the file so FORTRAN can use the
READ statement to read the file.  It would also be nice if the records
could be variable length.
                    Thanks for your help,
