You can do it if you know the maximum  length (which  you probably do
if it is a file with carriage control).   Note that  this is standard
Fortran 77, not VMS specific,  though of  course the carriage-control
problem is.  

      SUBROUTINE READREC(STRING,UNIT)
      CHARACTER STRING*80
      INTEGER UNIT
      READ(UNIT,'(A)')STRING
      RETURN
      END

Not knowing anything about vax-11 C, I'm not sure  the proper calling
sequence for this routine from C, but I'm sure it can be done.  

Of course, if you have control over the program writing the files the
simplest thing to do would probably be  to put CARRIAGECONTROL='LIST'
in the open  statement for  the output  file, and  thus avoid FORTRAN
carriage-control altogether.
