This is a short description of the VAX/VMS device driver disassembler 
routine package. It features automatic label generation and system
symbol substitution where appropiate (and considered useful).
All programs were running under RSX11M (for my convenience, since the
VAX is at a development site and I have my PDP-11 at home). The files
from VMS can be copied to RSX either by tape or by DECNET.

You should obtain/receive 5 files:

               lines
 CAMINFO.TXT  -  68 - this file.
 CAM.PAS      - 550 - the disassembler source.
 STB.PAS      - 121 - the symbol table file cracker (from SYS.STB).
 SYM.PAS      - 163 - the routine to substitute symbolic names.
 VAXINSTR.TXT - 312 - a text file containing the VAX instruction set 
		      definitions.

The programs were successfully compiled using OREGON PASCAL V2. There
may come up problems arising from different data type definitions when
using other PASCAL implementations.

All programs are currently designed only for the special purpose
of disassembling CONINTERR.EXE, so you should have to put in some effort
to do parameter/filename substitution and such. I would be very happy
to get back any enhanced versions, as I could re-distribute them at a
later time. 

Data flow:
                 input		  output	 temporary
   STB.PAS	SYS.STB		SYS.LST

   CAM.PAS	CONINTERR.EXE	MACRO32.LST	MACRO32.TMP
		VAXINSTR.TXT

   SYM.PAS	MACRO32.LST	CI.LST
		SYS.LST

Run program STB one time to get the disassembled system symbol table
text file SYS.LST.

Run program CAM to do the disassembly of the .EXE driver code. CAM
should be of more general use, but it was designed for driver dis-
assembly (no image header processing etc.). A file MACRO32.LST will
result containing the disassembled lines. 

Run program SYM to substitute symbolic names for system addresses
(8000xxxx) where appropiate. This eases reading the disassembled code
and is useful when linking the disassembled/assembled macro source
deck using another VMS version with new system space addresses defined.
The net result is CI.LST which is a macro source file of the disassembled
driver routine. No .TITLE / .PSECT etc. are generated, just a raw macro
source results, which must be edited to be acceptable to MACRO32.

The included file CONINTUCB.TXT is just a description of the UCB fields
used by CONINTERR decoded from a disassembly of CONINTERR.EXE for your
interest.
