ADD EXPORT
/OPTIONS= { [NO]DATA_CONVERSION | [NO]NAME_CONVERSION
| [NO]PURGE_VERSIONS | [NO]TYPELESS_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:
• 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.
• 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.
• 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.)
