Indicates the type of the executor node.  Possible node types are

                    ROUTING IV
                    NONROUTING IV
                    AREA

 The default depends upon the DECnet license installed.  If the
 full function kit is installed, the default is ROUTING IV; if the end
 node kit is installed, the default (and only possible value) is
 NONROUTING IV.

 A routing node has full routing capability.  A nonrouting node (or end
 node) can deliver packets to or receive them from any node, but
 cannot route packets from other source nodes through to destination
 nodes.

 An area node is a level 2 router that can route packets between areas.
