        !            25: access you can send and receive queries by electronic mail.  You can
        !            26: use this technique on any X25Net or Arpanet site when you want the

        !            30: HOW TO PREPARE YOUR NAME SERVER MESSAGES
        !            31: 
        !            32: Address your messages to the registrar at the CSNET Service Host:
        !            33: 
        !            34:         To: registrar@csnet-sh
        !            35: 
        !            36: You will receive an automatic answer to your query by message from
        !            37: NS_Service@CSNET-SH.
        !            38: 
        !            39: The subject field of the message you send will not be read by the Name
        !            40: Server, and may contain any text (or no text).
        !            41: 
        !            42: The body of the message should contain only the commands and keywords
        !            43: for the query, and no other text.  The general form is:
        !            44: 
        !            45:         whois
        !            46:         exact
        !            47:             keyword1 keyword2 ...
        !            48:         end
        !            49: 
        !            50: The words "whois", "exact", and "end" must each begin in column 1 of
        !            51: a new line.  The keywords may begin anywhere except column one.  Any
        !            52: number of keywords, possibly extending over more than one line, is
        !            53: acceptable.
        !            54: 
        !            55: Table ns-3.1 is similar to Table ns-2.1 (in Message ns-2), but shows
        !            56: both interactive query commands and the equivalent forms that you
        !            57: should use in your message.
        !            58: 
        !            59: 
        !            60: COMPOSING YOUR QUERY
        !            61: 
        !            62: The selection method used in the name Server is that of the "inverted
        !            63: index".  Each word in each entry is indexed separately, and, in
        !            64: general, the Name Server selects only on whole words.  A search
        !            65: specification consists of one or more words, and selection occurs when
        !            66: all the specified words are present in an entry.  It is not possible
        !            67: to specify other types of relationships between words.
        !            68: 
        !            69: A word is a string of characters between two delimiters. The delimiters
        !            70: recognized by the Name Server are:
        !            71: 
        !            72: 
        !            73:        <space>  <tab>  <end-of-line>  ;  .  ,  (  )  &  #
        !            74: 
        !            75: 
        !            76: A CAUTION ABOUT "%" 
        !            77: 
        !            78: Please note that the "%" character is NOT a delimiter at the present
        !            79: time.  For this reason, the Name Server treats "name%host" as a single
        !            80: word but "name.host" as two words.  At the time that the Name Server
        !            81: was designed, the full Arpanet address for a PhoneNet site was
        !            82: "name.host@csnet-relay"; at the current time, the Internet is in the
        !            83: process of preparing for domain-style addresses, and the Internet
        !            84: address which is recommended by the Arpanet Network Information Center
        !            85: is "name%host@csnet-relay".  
        !            86: 
        !            87: The reason is that many sites are now including a domain name to the
        !            88: left of the "@", for example, "name%[email protected]".  The
        !            89: use of "%" clarifies the distinction between hosts and domains.  When
        !            90: the domain system is fully implemented, this special use of "%" will
        !            91: probably be discarded.  However, if "%" remains special, the Name
        !            92: Server will be changed to treat "%" as a delimiter.
        !            93: 
        !            94: 
        !            95: REVISING THE DATABASE
        !            96: 
        !            97: The CSNET Staff is in the process of revising the Name Server database
        !            98: to update the old relay names, "udel-relay" and "rand-relay" and
        !            99: replace them with "csnet-relay".  At the same time, all entries
        !           100: "name.host-relay" will be changed to "name%host@csnet-relay".
        !           101: 
        !           102: 
        !           103: SEARCHING FOR WORDS IN THE DATABASE
        !           104: 
        !           105: There are a few restrictions on the characters in a word: The words
        !           106: must be strings of letters and numbers, or of letters only, but not of
        !           107: numbers only, so that you cannot select on a zip code or a telephone
        !           108: area code.  You can select on "@", but only if it is in the middle of
        !           109: a word.  You can use the wildcards, "*" and "?" at the middle or end
        !           110: of a word, but not at the beginning.  Because the analysis of the
        !           111: words is done before the query is made, there is no method for
        !           112: "quoting" numbers, the "@", wildcards or delimiters to allow
        !           113: selection.
