Digital Fortran requires that character data be passed by descriptor. See the
DEC C (or VAX C) documentation for details on how to do this. If a proper
descriptor is passed, you can declare the argument in Fortran as
It is also possible to pass characters from C to Fortran using
byte arrays, though you need to either scan them after the fact
or pass the length too. You can EQUIVALENCE byte arrays to character
variables, with the same caution.
It is also easy to pass descriptors from C to Fortran...
