/IDENTIFICATION[="identification-string"]

    Describes and identifies a node. Service nodes include the
    identification string in service announcements. A service node
    announces its services at regular intervals established with the
    SET NODE command. Entering the LATCP SHOW NODE command or the
    DECserver SHOW NODE command generates a display that includes
    this identification string. By default, the identification string
    is the translation of SYS$ANNOUNCE.

    You cannot specify more than 64 ASCII characters in an
    identification string (a SYS$ANNOUNCE longer than that will be
    truncated to the first 64 characters). Enclose the string in
    quotation marks (" ").
