       DIRECTORIES }

    Optional.

                                   NOTE

       For clients operating in OpenVMS to OpenVMS mode, the
       server ignores the options in the export record and uses
       the settings required for OpenVMS to OpenVMS mode.

    Options for the specified directory:

    o  CASE_BLIND, CASE_SENSITIVE

       -  CASE_BLIND (default)

          The NFS server ignores the case of file names when looking
          up files.

       -  CASE_SENSITIVE

          The NFS server is case-sensitive when looking up files.
          For example, NFS would preserve the case in the file names
          AaBBc.TXT and AABBC.TXT, regarding them as two different
          files.

    o  DATA_CONVERSION, NODATA_CONVERSION

       -  DATA_CONVERSION (default)

          Converts the following kinds of sequential files:

          *  Variable

          *  Variable with fixed-length control (VFC)

          *  Fixed-record formats

          Converts sequential files according to the rules applied by
          the following record attributes:

          *  Carriage return/carriage control (CR)

          *  Fortran carriage control (FTN)

          *  Print file-format control (PRN)

          Stream formats are returned unconverted.

          The data in files with nonstream records cannot be written
          back to the file.

       -  NODATA_CONVERSION

          File data is considered raw and is returned without
          conversion. Nonstream records are returned with their
          record control information mixed with the record data.
          Files can be rewritten randomly.

    o  NAME_CONVERSION, NONAME_CONVERSION

       -  NAME_CONVERSION

          A non-OpenVMS client can create files with mixed-case
          names and names containing characters that are invalid
          for OpenVMS file names. The server converts such names to
          valid OpenVMS file names, and reverses the conversion when
          displaying the file names to a non-OpenVMS client.

       -  NONAME_CONVERSION (default)

          Clients can only create files with valid OpenVMS names.
          The server performs case-insensitive lookups and displays
          directories in lowercase.

    o  PURGE_VERSIONS, NOPURGE_VERSIONS

       Default: NOPURGE_VERSIONS

       Deletes multiple versions of files. (The NFS CREATE and RENAME
       calls can create multiple versions. The NFS READDIR call can
       sense multiple versions.)

    o  TYPELESS_DIRECTORIES, NOTYPELESS_DIRECTORIES

       -  TYPELESS_DIRECTORIES

          Removes .dir.1 from the name of directories. A naming
          conflict could arise if, for example, two files exist in
          the parent directory:

          DOVE.;1 (regular file)
          DOVE.DIR;1 (directory file)

          The name of the regular file is returned as dove., rather
          than dove, if a file and a conflicting directory exist.

       -  NOTYPELESS_DIRECTORIES (default)

          Returns names as file.ext and file.dir.
