Copyright(c) Maynard Electronics, Inc. 1984-89
Name: mayn31.h
Date Updated: $./FDT$ $./FTM$

Description: Maynard's 3.1 Format... See the Document for
complete details.
$Log: T:/LOGFILES/MAYN31.H_V $
*
* Rev 1.15 10 Jan 1995 14:27:14 GREGG
* Added code to deal with continuation bits wrongly set in DDBs.
*
* Rev 1.14 01 Aug 1994 21:56:42 GREGG
* Added replaced internal structures in the Novell OS Info with packed
* versions. The unpacked versions made the structure size different than
* the size on tape! MAYN31RD.C rev 1.54 is needed with this change.
*
* Rev 1.13 17 Jan 1994 14:56:56 GREGG
* Unicode fixes.
*
* Rev 1.12 12 Jan 1993 11:10:50 GREGG
* Fixed problem with not recognizing we had repositioned and needed a new DBLK.
*
* Rev 1.11 06 Jan 1993 17:20:28 GREGG
* Added pad stream to skip the pad data.
*
* Rev 1.10 18 Nov 1992 10:39:30 HUNTER
* Bug fixes
*
* Rev 1.9 11 Nov 1992 09:48:54 HUNTER
* Changes for Streams.
*
* Rev 1.8 24 Jul 1992 14:41:10 NED
* Incorporated Skateboard and BigWheel changed into Graceful Red code,
* including MTF4.0 translator support, adding 3.1 file-system structures
* support to the 3.1 translator, additions to GOS to support non-4.0 translators.
* Also did Unicode and 64-bit filesize changes.
*
* Rev 1.7 28 Apr 1992 09:35:54 HUNTER
* Added "vblk_scan" variable to 3.1 environment.
*
* Rev 1.6 12 Dec 1991 10:49:36 HUNTER
* Changed VBLK identifier defines.
*
* Rev 1.5 17 Nov 1991 17:38:50 GREGG
* Changed value of DB_VAR_BLKS_BIT (it was stepping on ARCHIVE_BIT).
*
* Rev 1.4 07 Nov 1991 15:23:36 HUNTER
* VBLK - Further Variable Block support
*
* Rev 1.3 29 Oct 1991 10:12:50 HUNTER
* VBLK - Added VBLK structure and new bits to support Variable length blocks.
*
* Rev 1.2 22 Jul 1991 11:50:50 GREGG
* Added EOS_AT_EOM attribute bit.
*
* Rev 1.1 10 May 1991 14:25:46 GREGG
* Ned's new stuff.
Rev 1.0 10 May 1991 10:17:38 GREGG
Initial revision.
