E13 I want to write the value of a KEYWORD parameter in Fortran code to

    a file, but nothing I try works.

    Cactus KEYWORD and STRING parameters are not stored as Fortran strings
    (they are pointers to C strings) so you need to convert them first.
    Use the routine CCTK_FortranString to copy them to a locally defined
    Fortran string, then you can manipulate them as usual. If you just
    want to print the value to the standard output there is also the
    routine CCTK_PrintString.
