1 Export_File
!
An export file is created using the EXPORT command.  This is a text
file containing node registration information read from some directory
service.

This file can be used as input to the IMPORT command to move node
information from one directory service to another, or to verify the
information in one or more directory services.  It can also be edited
to change any information (such as the NSAP IDP used by the network)
and used to bulk modify the contents of the directory service.

The file contains the following sections.

    <type-and-version>

    <directory-service-information>
    <node-registration-information>

    <directory-service-information>
    <node-registration-information>
        :
    <directory-service-information>
    <node-registration-information>

The directory service and node registration information sections are
repeated as often as necessary to ensure that the appropriate directory
service information is associated with the correct node registration
information.

2 Type_and_Version
!
This section contains the following information.  Lines beginning with an
equals sign (=) contain control information (the equals sign must be
in the first character position, or it is treated as the first character
of a node name).

  =Type DECnet Node
  =Version 1

These lines specify the file contents and version.  The values shown above
are the only currently recognized values.
!
2 Directory_Service_Information
!
This section contains the following information.  Lines beginning with an
equals sign (=) contain control information (the equals sign must be in
the first character position, or it is treated as the first character of
a node name).

  =All       Address Prefix                 ???

  =DECdns    Name Template                  ???:.???.*
  =DECdns    Synonym Directory              .???
  =DECdns    Reverse Address Directory      .???

  =LocalFile Name Template                  ???*

  =PhaseIV   Name Template                  *

The information specified in this section provides default values for use
when importing into the indicated directory service ("All" indicates
information that is used for all directory services).

Lines from this section can be repeated further down in the file, to
change the supplied information.  For example, this is useful when a
file contains node information that is to be registered into several
directories (specified using the Name Template value).

Initially, the value for each piece of information is set to "unknown",
by writing question marks (???) to the file.  If the EXPORT command can
determine an appropriate value for any of these, it places that value in
the file instead.  This is possible only for the directory service you
are exporting from.

When the file is read by the IMPORT command, only those lines intended for
the target directory service are examined.  All others are ignored, and
can contain invalid values without causing an error.  Also, each line in
this section has an equivalent IMPORT command parameter.  If the parameter
is specified in the IMPORT command, then the value contained in the file
for that parameter is ignored, and can contain an invalid value without
causing an error.  

See the IMPORT command for an explanation of each parameter value.

2 Node_Registration_Information
!
This section contains the node registration information.  These lines must
not begin with an equals sign (=) in the first character position.  If a
node uses an equals sign as the first character in its name, indent the
name by at least one space.

The format for a node information line is:

  name  synonym {TOWER=tower, TOWER=tower, ..., TOWER=tower}

Where:

  name      The terminating part of the name for the node.  This is
            generally the part of the name that is the same regardless
            of the directory service.  For example, "MailHub" is the
            terminating name for the following:

                Local:      MailHub
                DECdns:     MyCo:.Sales.MailHub

            When importing into the Phase IV Database, this is ignored
            and the synonym field used used, if a synonym is defined.
            If a synonym is not defined, and the name is not Phase IV
            compatible, an error results.

  synonym   The Phase IV synonym for the node, if any.  This is optional.

  tower     A tower value for the node.  The format for an individual
            tower is the same as it is in a TOWERS parameter.  See the
            ADDRESS_TOWERS topic for a description of this format.

            All directory services except the Phase IV database support
            multiple towers.  If importing into the Phase IV Database,
            the first Phase IV compatible tower is used.

            The braces surrounding the list of towers are required.

For example:

  MailHub  MLHUB  {Tower=12.2, Tower=37:840:0001:08-00-2B-0D-E9-B1:21}
