This command gets the tower set for any node in the local name file which has only a simple address defined. GET TOWERS [file-name] [ALL] When you use CREATE to create an initial local name file, the addresses are placed in the file as simple Phase IV addresses. Similarly, when you edit the local name file, you can specify the node addresses as simple Phase IV addresses or DECnet-Plus NETs (network entity titles). The GET TOWERS command is used to obtain the full DECnet-Plus tower sets for these nodes by using the simple addresses. The GET TOWERS command scans the local name file for any node definitions that contain an empty TOWERS parameter or no TOWERS parameter. For each such definition, it uses the ADDRESS parameter to attempt a connection to the specified node. If the connection succeeds, it obtains the real tower set information from the node, and adds the appropriate TOWERS parameter to the node definition. If the connection fails, it leaves the TOWERS parameter empty, allowing GET TOWERS to be retried at a later date. To update the tower set information for some subset of the nodes, edit the text file, delete the TOWERS parameter from the appropriate node definitions, and issue the GET TOWERS command. The command obtains tower information for only those node definitions that do not already have a TOWERS parameter specified. To update the tower set information for all nodes in the local name file, issue the GET TOWERS ALL command. The command obtains tower information for all nodes listed in the file. If it cannot obtain tower information for any particular node, it will leave the old tower information for the node unchanged. Use of this command is optional. You can specify the tower set for any node when you edit the local name file, or you can specify only the simple address. If you specify only the simple address, network connection establishment might take longer for some nodes. If you do not specify a file name in the GET TOWERS command, a default file name of SYS$SYSTEM:DECNET_LOC_NODE_DEFINITIONS.TXT is used.
