   The on-line documentation will be maintained as (userguides.

   The first implementation of a Network Journal Submission and Delivery
   system is now experimentally up.  This system allows use of the NIC's
   NLS Journal System without entering NLS.  Network users may submit
   text files written on their host systems using their mail subsystems
   (e.g. SNDMSG, FTP, TELNET).  The mail will then be converted at SRI-
   ARC into NLS files, journalized, and sent to the specified recipients
   according to their preset Journal delivery options.  A newly added
   option permits the user to receive automatic Journal delivery (of
   citations to journalized documents) at his host via the Network mail
   protocol.

Overview

   Network mail sent to SRI-ARC (NIC) will be entered into the NIC
   Journal system if a slash appears in the user-name.  To get the mail
   to the NIC, you may use either the FTP, TELNET, or mail subsystem
   provided by your local system.

   The author's NIC Ident(s) are assumed to appear before the slash; the
   recipients' NIC Ident(s) after it.  Idents should be separated by
   spaces.  (See scenarios in branch 3)
   (e.g. jew / mdk dhc)

RFC 543         Network Journal Submission and Delivery     13 July 1973


   When this format is detected by the NIC, the Network Journal system
   will be invoked.  At SRI-ARC the mail will be transformed into an NLS
   file, assigned a unique catalog number, stored permanently under that
   number, and a notice of it will be sent to all the listed recipients.
   If the slash is not found, the mail will be handled in the normal
   way.

   Delivery of Journal citations may now be obtained via the Network (as
   well as to an NLS file at SRI-ARC and in hard copy).  If you wish to
   receive your Journal mail at you host computer, contact the NIC (see
   RFC510 -- 16400,).

   A more detailed description follows.

NETWORK JOURNAL SUBMISSION

   The remote user prepares the text of his Journal article in his host
   using whatever tools he has available to him.  He may wish to prepare
   long articles beforehand using his text editor (e.g. TECO if he's a
   TENEX user).  For short messages, he may be content with the basic
   editing features (such as backspace character and line delete)
   provided by his submission subsystem.

Connecting to the NIC

   To get the mail to the SRI-ARC FTP server, you must either:

      1) via FTP and TELNET mail subsystems, connect to SRI-ARC's FTP
         server process, then issue the FTP mail command, or

      2) use the mail subsystem provided by your local system.

         For TENEX SNDMSG mail: put "@nic" at the end of the "User:"
         field.
            (e.g. jew / mdk dhc@nic)

         If you wish to send the mail as a SNDMSG message to  some
         people as well as submit it to the Journal, you may treat the
         Journal form as one name, follow it with a comma, and then list
         other names of which SNDMSG is aware, separated by commas.
            (e.g. jew/mdk dhc@nic, meyer, white)

Specifying Authors and Recipients

   The user invokes Network Journal submission via his mail subsystem.
   Network Journal Submission is invoked by a user-name field of the
   following format:

RFC 543         Network Journal Submission and Delivery     13 July 1973


      author $(SP author) [SP] / [SP] recipient $ (SP recipient) [SP]
      [ ; conversion algorithm]

         "$(..)" means "any number of occurrences, possibly
                 zero, of what's inside the parentheses"
         "SP" means "space"
         "[..]" mean "the contents of the brackets are optional"

   i.e., author(s), slash, recipient(s), optional semicolon and
   conversion-algorithm

      e.g., jew/mdk rww   cr    dcs rww jcn / sri-arc ;h

   'Author' is the NIC Ident of (one of) the user(s) submitting the
   article, and 'recipient' the Ident of (one of) its intended
   recipient(s).  An Ident, as usual, may designate either a "group" or
   an "individual".  SRI-ARC will verify the idents.  If it finds them
   correct, it will accept the mail.  An invalid Ident will cause the
   mail to be rejected; the user will get an error message and have to
   start over.  The first author Ident will be taken to be the clerk.

   If the SRI-ARC mail subsystem finds the slash in the user-name field,
   the Network Journal Submission system will be invoked; otherwise, the
   mail will be treated as normal Network mail (delivered to the
   directory specified by the user-name).

Specifying an NLS Conversion Algorithm

   Optionally, the sender may specify the algorithm by which his
   sequential message file is to be converted to NLS format.  This
   choice is made by inserting:

      ; conversion algorithm

   anywhere in the 'user-name' field (e.g. jew/mdk rww;s).  (This should
   be before the "@nic" for SNDMSG.)  Legal values for conversion-
   algorithm are:

      s -- Insert Sequential, each line an NLS statement (default
      conversion-algorithm)

      a -- Insert Assembler with structure

      m -- Insert Assembler without structure

      h -- Heuristic Insert Sequential, double <CR>s indicating end of
      statements, assuming no right justification in the source file.




Meyer                                                           [Page 3]

RFC 543         Network Journal Submission and Delivery     13 July 1973


      j -- Heuristic Insert Sequential, double <CR>s indicating end of
      statements, assuming right justification in the source file (for
      those who put multiple spaces between words to line up the right
      margin, multiple spaces will be removed)

         By "Heuristic Insert Sequential", we mean that the Insert
         Sequential algorithm attempts to be smarter about handling
         statements and levels.  Statements are delimited by two
         successive carriage returns.  Statement level will be
         determined by the amount the statement is indented.  If it is
         indented more than the previous statement, it will be taken to
         be a substatement and put down a level; if it is the same as
         the previous statement, it will be on the same level.  If the
         statement is indented less than the previous statement, the
         program will look for a past statement with the same
         indentation and put it at that level, The indentation of a
         statement is taken to be that of either the first or second
         line of the statement, whichever is less (to ignore paragraph
         indentation, for example).  This is good from 1 to 12 levels.
         Carriage returns at the end of full (within 10 characters of
         the right margin, i.e. 62nd column) lines are replaced by
         spaces.

         This algorithm is an attempt to answer a very difficult need.
         It won't always do just the right thing, but it should often
         provide the intended result.  The user is encouraged to
         experiment with it; suggestions will be welcomed.

Titling the Message

      Once the conversion has been performed, an optional title,
      signaled by the label 're:'. 'title:', or 'subject:' is searched
      for in the first statement of the message text.  (The label may
      either be all upper or all lower case, or the first character
      upper and the rest lower case.)  If a label is found anywhere in
      the statement, the line of that statement beginning with the first
      non-blank character following the label and going up to the first
      carriage return (and line feed) or else to the end of the
      statement is taken as the Journal title, and the statement
      containing the title is deleted from the file,  Any substructure
      will be moved up a level.

   The submission is equivalent to the NLS 'Submit Message' command if
   th NLS file (after the title statement (if any) has been deleted) has
   only one statement in it besides the origin statement; in such a
   case, the message in its entirety will be delivered as part of the
   Journal citation.  Otherwise the Network submission is equivalent to
   'Submit File'; only a reference to the Journal document will be
