- This file briefly describes the QWK file format.
-
- The following is an abbreviated version of Appendix G of DELUXE.DOC:
- ──────────────────────────────────────────────────────────────────────────
- All of the messages in a mail packet are contained in a file
- named MESSAGES.DAT. The file's logical record length is 128
- bytes. The first record of MESSAGES.DAT always contains
- Sparkware's copyright notice produced by The Qmail Door.
- Messages start in record #2 and use this format:
-
- Starting Position,Length Description
- ------------------------ ----------------------------
- 1,1 Message status flag
- 2,7 Message number
- 9,8 Date (MM-DD-YY)
- 17,5 Time (HH:MM)
- 22,25 To
- 47,25 From
- 72,25 Subject
- 97,12 Password
- 109,8 Message reference number
- 117,6 Number of blocks
- 123,1 Message status
- 124,2 Conference number
-
- The text of message continues in the next record. You can
- find out how many blocks make up one message by looking at
- the value of "Number of blocks". Message text is delimited
- by a pi symbol (ASCII 227) between lines.
-
- The xxx.NDX files contain record numbers that point into the
- MESSAGES.DAT file for actual messages. Each conference that
- contains messages has its own "xxx.NDX" file. The "xxx" is
- the conference number for the index file.
-
- Each .NDX file uses a five byte logical record length and is
- formatted to:
-
- Starting Position,Length Description
- ------------------------ ------------------------
- 1,4 Record number of message
- in MKS$ format.
- 5,1 Conference number.
- ──────────────────────────────────────────────────────────────────────────
-
- The formula for converting x, a LONGINT in MKS$ format, to MKSToNum, a
- binary integer, is:
-
- MKSToNum := ((x AND NOT $ff000000) OR $00800000)
- SHR (24 - ((x SHR 24) AND $7f));
-
- It's not pretty but it works (and it only handles positive numbers).
-
- The CONTROL.DAT is a text file containing information about
- the host BBS and conference information. Here is a sample
- one with comments:
-
- Ivo Andric Memorial BBS ;bbs name
- Victoria, BC, CANADA ;bbs location
- 604-380-0297 ;bbs number
- Gwen Barnes, Sysop ;format is "First Last, Sysop"
- 20001,ANDRIC ;DOOR_SERIAL,PACKET_ID
- 01-09-1991,14:54:44 ;mm-dd-yyyy,hh:mm:ss ..pkt time
- GREG HEWGILL ;user name
- ;name of QMENU file if exists
- 0 ;unknown
- 0 ;unknown
- 254 ;total # of conferences - 1
- 0 ;# of first conf
- Local ;name of conf (10 chars max)
- 1 ;# of second conf
- I_Central ;etc...for 255 confs
- ...
- 255 ;this is the 255'th conf (#24
- U_C_Prog ; is omitted from this packet)
- HELLO ;filename of welcome file
- NEWS ;filename of news file
- GOODBYE ;filename of goodbye file
-
- If you're looking at a real CONTROL.DAT, any further lines you can
- ignore because current mail doors don't generate it (it's obsolete).
