    1.0  SYSTEM FILES
    -----------------

    D'Bridge is a complex program that uses quite a few control, storage
    and history files to store system information.  This document lists
    these file structures so that programmers may access them in utility
    programs.

    While D'Bridge is an "all-in-one" product that encompasses all major
    operations of running a Fidonet system; there are many control-files
    that act as "hooks", allowing you to customize the software for your
    own unique requirements.

    Structures will be listed in the following sections, but here is a brief
    summary of all files used directly by D'Bridge:

    2.0  PARAMETER FILE
    -------------------


    D'Bridge uses a text-file called DBRIDGE.PRM to store its parameters.
    The structure of this file will change in future versions, but this
    is the definition for version 2.95.  When using this chart, make sure
    that you understand that "Line" doesn't really mean the literal line
    of the text file, but the currently processed line.  Fields that have
    an asterisk (*) in the in "Column" field are called LISTS.

    LISTS are fields that contain any number of lines.  The first line of
    a list contains the number of lines in the list.  If a zero is found,
    the list is empty.

    DBRIDGE.PRM must begin and end the same way it began.  Specifically, the
    first and last lines should read something like:

    Version 2.95 Pre-release Beta / 15 December 2007

    If it does not, then you cannot assume that this information is correct.
    This document will be revised as D'Bridge does.  This data is provided
    for your information only.  Do not count on it to remain stable through
    future releases.  This is changed even during the beta cycle; only the
    first 20 fields will never be changed.

    DBRIDGE.AUT is a more stable, but not as timely source of information.
    The import format is easier to read because it is keyword, not position
    sensitive.  Refer to the following section for keyword information.

    3.0  EXPORTED CONFIGURATION LANGUAGE
    ------------------------------------

    To maintain compatibilty between versions of D'Bridge, an "exported
    configuration language" has been established as a means of upgrading
    without losing parameters.  When a new version is installed, D'Bridge
    will import the configuration from a file called DBRIDGE.AUT.

    Following is a syntax chart of all the keywords used in the current
    software version:

      4.0 MESSAGE STORAGE STRUCTURES
      ------------------------------

      D'Bridge can use different storage methods to store messages on
      disk.  These particular methods were chosen for compatibility with
      popular bulletin board systems.  Following are the file-structures
      used by D'Bridge for EMAIL message storage:



         FIDO

         When Fido-style storage is chosen for an area, a dedicated sub-
         directory will be created.  This directory will contain one file
         for each message stored.  The format for the filenames is:

            <message#>.MSG    ie. 1.MSG, 2.MSG ... 9999.MSG


         Following is the Turbo-Pascal definition of the .MSG file format:


            FIDO_message = record
              msg_from,
              msg_to         : array [1..36] of char;
              subj           : array [1..72] of char;
              msg_date       : array [1..20] of char;
              times_read,
              dest_node,
              orig_node,
              cost,
              orig_net,
              dest_net       : integer;
              date_written,
              date_arrived   : longint;
              reply          : integer;
              attributes     : word;
                            (* Bit 0    Private
                                   1    Crash
                                   2    Message read
                                   3    Message sent
                                   4    File-attach
                                   5    Forwarded
                                   6    Orphan
                                   7    Kill/sent
                                   8    Local message
                                   9    Hold
                                  10    ???
                                  11    File-request
                                  12    Return-receipt requested
                                  13    Return-receipt
                                  14    Audit-trail requested
                                  15    Update-request  *)
              unreply        : integer;
              message_text   : array [1..???] of char;
                            (* The message text field contains text of
                               any length, terminated with a null (0) byte *)
            end;



       QUICKBBS

       When QuickBBS-style storage is chosen for an area, messages are stored
       in a 5-file database designed by Adam Hudson.  The file-formats are
       defined in the following Turbo-Pascal definition:


            MSGHDR.BBS     QuickBBS message header file

            QuickBBS_header = record
              message_number,
              reply,
              unreply,
              times_read,
              starting_record,
              number_of_records,
              dest_net,
              dest_node,
              orig_net,
              orig_node            : integer;
              dest_zone,
              orig_zone            : byte;
              cost                 : integer;
              msg_attributes,     (* Bit 0   Deleted

              msg_from             : string[35];
              subj                 : string[72];
            end;


            MSGIDX.BBS     QuickBBS message index file

            QuickBBS_index = record
              message_number       : integer;
              area                 : byte
            end;


            MSGINFO.BBS    QuickBBS message summary file

            QuickBBS_info = record
              low_message,
              high_message,
              total_messages    : integer;
              active_messages   : array [1..200] of integer
            end;


            MSGTOIDX.BBS   QuickBBS message-to index file

            QuickBBS_to_index = string[35];


            MSGTXT.BBS     QuickBBS message text file

            QuickBBS_text = string[255];


    5.0  D'BRIDGE FILE STRUCTURES
    -----------------------------



    Following are Turbo-Pascal or text-file definitions of the data, history
    and control files used by D'Bridge.  These structures are subject to
    change in future releases...




       AREAS.BBS

       Each file area where requests are allowed may have an AREAS.BBS file.
       This contains single-line descriptions of each file and will be sent
       back to the requesting system in the file-request "status" message.
       This is a text file of one record per line with the following format:

       <filename> <description>




       AREAS.TXT

       This file contains a list of possible ECHOmail conferences and their
       respective descriptions.  In the Fidonet EMAIL network, a file called
       FIDONET.NA defines all the ECHOs available.  Rename FIDONET.NA to
       AREAS.TXT to use it with D'Bridge.  The file is used to automatically
       add descriptions to the ECHOmail areas when the are auto-added.  The
       following format is used:

         <area tag> <description>




       CALLER.INF

       When D'Bridge receives a function-request, it writes a text file
       called CALLER.INF in the current directory.  This file contains
       the following information about the caller online:

            <address>
            <system name>
            <system operator>
            <inbound files directory>


         LINExxx.CFG

         This file contains the modem/communication parameters.  The file-
         structure is as follows:

         communication =
           record
             active : record
                        dial_300,

                        dial_19200      : string[20];
                        connect_strings : pointer;
                      end;
           modem : array [1..3] of
                     record
                       portname       : string[4];
                       maxasyncbaud   : longint;
                       locked         : boolean;
                       modem_init     : pointer;
                       modem_answer   : string[40];
                       modem_timeout,
                       base,
                       irq            : word;
                       mcf            : string[8];
                       description    : string[34];
                     end;

             collision_detect,
             offhook,
             dimesaver            : boolean;
             max_rings,
             autoInit_time        : word;
             printer_port         : string[40];

             title_indent         : byte;
           end;
       

         COSTBASE.DB1/DB2

         The COSTBASE files are created and maintained by the B-TREE FILER
         routines available from Turbo-Power Software.  They contain the
         cost and control data from the ACCOUNTING/TRANSLATION screen.


         costbase_structure =
           record
             del            : longint;
             RECTYPE        : char;
             prefix         : string[20];
             dial_as        : string[30];
             location       : string[20];
             reserved       : array [1..16] of
                                char;
             xref_prefix    : string[20];
             costing_source : char;
             CostMatrix     : costing_matrix
           END;



         costing_matrix =
           record
             start_time,
             end_time           : array [1..10] of

         COSTING.XDC

         Every night at midnight, D'Bridge creates an exported costing file.
         This file is designed for compatibility between versions or to send
         costing data to another system.  This is a text file that contains
         a header line and two kinds of data lines.  A typical costing entry
         looks like this:


           1-418                1-418                          Quebec
            SMTWTFSH 0000 0800 NCI   0.3700  60.0   0.3300  60.0
             MTWTFS  1800 0000  CI   0.4800  60.0   0.4200  60.0
             MTWTF   0800 1800  CI   0.7500  60.0   0.6600  60.0
            S      H 1800 0000  CI   0.4800  60.0   0.4200  60.0
            S     SH 0000 2400 NCI   0.3700  60.0   0.3300  60.0



         The first line is the country code/city code for the entry.  It must
         start in column 1.  The next lines contain the actual costing data
         and start at column 2.  Following is the field definition:


         Field                  Column   Description

       DB-IO.DAT

       If the environment variable DB-IO-LOG is set, all communications data
       will be written to the file C:\DB-IO.DAT.  This is just a debugging
       tool, and keep in mind that it can fill a hard drive quickly...

       Each character sent to or recieved from the modem will be written to
       the file in the following two-byte format:

           Byte 0 - Data byte (if applicable)

           Byte 1 - Control byte

                    0 - Receive data
                    1 - Transmit data
                    2 - Output buffer purged

       DBRIDGE.AFF and DBRIDGE.TFF

       This the the AREAFIX-forwarding queue file.  AREAFIX requests that
       are forwarded to another system are stored here.  This text file has
       the following format on each line. Note that for EchoFILE/TIC
       requests the TFF file is used.

       <feed address> <remote address> <area tag> <priority> <password>



       DBRIDGE.AFQ and DBRIDGE.TFQ

       This is the AREAFIX-forwarding holding file.  Pending AREAFIX
       requests are stored here until the timeout date.  The text file
       has this format on each line. Note that for EchoFILE/TIC
       holding, the TFQ file is used.

       <date> <area tag> <feed address> <remote address>

              end;


         DBRIDGE.DRQ

         If this file exists, the system will drop Areafix/Filefix
         requests that match, per-line. The format of this text file
         is the area name (Echomail or TIC), a space, then the system's
         address. For example:

              <Areaname>  <system>



         DBRIDGE.DSI

         The D'Bridge system information file is a read-only file for utility
         authors.  It may not be modified, as the information is secured by

         DBRIDGE.NDH

         If this dummy/semaphore file exists, D'Bridge will not add the
         area description to the Echomail History file.


         DBRIDGE.HIS

         D'Bridge uses this file to track outbound XMAIL filenames:


           node_history =

               bad_connects : integer
             end;


         DBRIDGE.LNR

         This file contains one line of text of the last NETmail
         received on the system addressed to the Sysop. For example:

         From Joe Smith to Nick Andre




         DBRIDGE.LRQ

         For QuickBBS, DBEDIT stores the LASTREAD pointers in this file:


            Quickbbs_lastread = record

         DBRIDGE.WIS

         The D'Bridge "wisdom control file" may contain a customized message
         to be displayed upon startup.  This replaces the standard definition
         that appears in the box at the bottom of the screen when the system
         is coming online.

         This file may have 1-13 lines of text, 65 columns in width.


         DBRIDGE.WLF

         This file can be created by your own batch files or by 3rd-party
         programs to write an entry to the system log. This is just a one-
         line of text. D'Bridge will erase this file after the log entry
         is added.



         DBUTIL.BSY

         This file is created by DBUTIL when it executes, and erased when
         completed. D'Bridge will wait for this file to vanish, before
         performing a QueueScan, CompressXMAIL, moving mail to BinkD
         staging, or immediately after a dialup session has ended.


         ECHOMAIL.CTL

         If this text file exists, D'Bridge will only scan the ECHOmail areas
         listed within.  If it doesn't exist, all ECHOmail areas are scanned.


         FILEBASE.DB1/DB2

         The FILEBASE files are created and maintained by the B-TREE FILER
         routines available from Turbo-Power Software.  They contain the
         compiled filebase data.


           FILEbase_structure = record

    6.0  DISK-BASED QUEUE
    ---------------------


    D'Bridge has a disk-based queue for XMAIL, file-transfer and AREAFIX
    requests.  This queue works independently of the NETmail area and may
    be accessed by user-written programs.  All queue entries reside as files
    in the specified "queue" directory; the address is encoded in the file-
    name as base-36 numbers.


    The filenames of queue entries use the following format:

       t-zzzNNN.nnn           H-00102X.00G
           -or-                   -or-
       t-POINT-ppp            H-POINT.005


    Where: t     is the entry type (A/B/C/H/I/N/Q)
           zzz   is the base-36 ZONE address
           NNN   is the base-36 NET address
           nnn   is the base-36 NODE address
           ppp   is the base-36 POINT address



    Base-36 numbers use the digits 0-Z to represent the numbers.  You will
    notice from the structure that the address is either 3-dimensional (ZONE,
    NET and NODE) or a POINT-address.  It is impossible to have a queue entry
    for a point of another system.


    The following queue entry-types are currently defined:


       A - AREAFIX request packet

       An "A" queue entry is an outbound AREAFIX request; this is a NETmail
       message that is destined for the specified system.  It must always be
       associated with a "Q" entry-type that designates the packet priority.
       This packet is generated by using the REQUEST ECHOMAIL LINK, ALT-R
       option of D'Bridge.

       B - Inbound AREAFIX request/New ECHOmail link control file

       The "B" queue entry indicates either an inbound AREAFIX request or
       a request issued using the NEW ECHOMAIL LINK, ALT-N command.  These
       requests are usually processed immediately, but if there is a hold
       on ECHOmail forwarding because of a disk-space limit, these files may
       accumulate.  The "B" queue entries are text files in the following
       format:

          <priority><rescan><area listing><manual override>
          <area name>
          .
          .
          <area name>


          <priority>         is either N, I, C or H
          <rescan>           Should the area be rescanned?  Y or N
          <area listing>     Should an area listing be sent?  Y or N
          <manual override>  Is this a manual (ALT-N) entry?  Y or N

          <area name>        Either + or - then the ECHOmail tags to add
                             or remove from your LOCAL/ECHOMAIL AREAS screen.

       "B" queue entries are processed when an ECHOmail scan is done; any
       external program may add entries to the disk-based queue.


       C - Crash priority XMAIL

       "C" queue entries are XMAIL (compressed mail) packets with CRASH
       priority.  These will be sent during any event including the UNEVENT
       to the specified system.  This file contains any number of outbound
       mail packets.

       E - ECHOFILE request packet

       An "E" queue entry is an outbound FILEFIX request; this is a NETmail
       message that is destined for the specified system.  It must always be
       associated with a "Q" entry-type that designates the packet priority.
       This packet is generated by using the REQUEST ECHOFILE LINK, ALT-R
       option of D'Bridge.

       F - Inbound FILEFIX request/New ECHOmail link control file

       "F" entries are the same as "B" entries except it relates
       specifically to the FILEFIX system, not Areafix.


       H - Hold priority XMAIL

       "H" queue entries are XMAIL packets with HOLD priority.  These will
       never be sent unless there is a forced priority override or the
       operator uses the VIEW/MODIFY QUEUE command to force D'Bridge to call
       the specified system.  Typically, HOLD priority XMAIL is picked up
       by a "poll" from the destination system.

       I - Immediate priority XMAIL

       "I" queue entries are XMAIL packets with IMMEDIATE priority.  These
       will be sent immediately during any event; this priority overrides
       crash and all immediate queue entries will be sent before any other
       outbound traffic.

       N - Normal priority XMAIL

       "N" queue entries are XMAIL packets with NORMAL priority.  They will
       never be transmitted during the UNEVENT unless a forced priority has
       been specified or the operator uses the VIEW/MODIFY QUEUE command to
       force it to send.



       Q - General purpose outbound queue

       A "Q" queue entry is a text file that contains any number of lines,
       each of which contains one of the following formats:


          <priority> P

          A "P" entry indicates a "poll" with the specified priority.


          <priority> T <file path> <transmit filename> <kill>

          A "T" entry indicates an outbound file transmission.   Wildcards
          are not allowed here; all entries must specify full filenames and
          whatever programs add entries to the queue must do the wildcard
          expansion themselves.  This queue structure requires that both the
          full path of the file be specified as well as the transmitted file-
          name; this allows files to be transmitted different filenames than
          they have on disk. If the letter "K" exists on the end, the file
          will be deleted (killed) upon being transferred.


          <priority> F <filename>

          A "F" entry indicates a file request.  Filenames may include a
          path, but the file will be received into the inbound files
          directory unless you are requesting from a SEAdog or "Bark-style"
          system.  If the file exists in the specified path, an update-
          request will be generated, only receiving the file if a newer
          version exists.

          <priority> R <packet path> <transmit packet name>

          An "R" entry indicates an outbound AREAFIX request.  This is always
          associated with an "A" queue entry which contains an actual NETmail
          packet.

         The disk-based queue was designed to allow user-written programs to
         transmit files and XMAIL easily without using the DBUTIL program.
         Following is a sample routine to generate the queue entry filenames
         based on kind, ZONE, NET, NODE and POINT:


           function qname(kind : char;
                          zone,
                          net,
                          node,
                          point : integer) : string;

           function base36(n : integer) : maxstring;
           var d36 : string[36];
           i,j,k : integer;
           begin
             d36:='0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ';
             i:=n div 1296;
             j:=n mod 1296;
             k:=n mod 36;
             j:=j div 36;
             base36:=d36[i+1]+d36[j+1]+d36[k+1]
           end;

           begin
             if point<>0 then
               qname:=kind+'-POINT.'+base36(point)
             else
               qname:=kind+'-'+base36(zone)+base36(net)+'.'+base36(node)
           end;
