               ADDING A NEW TABLE AND COMMANDS TO DCNSPY


DEFINING THE TABLE MACRO

   The BEGSTR MACRO which defines your table must be copied into DCNSPY
and  changed  to  the right format. It ends up as a macro named XXXMAC,
where XXX is the table name. The BEGSTR entries must  be  changed;  for
example the BEGSTR entry

	WORD NXT		;NEXT JOB BLOCK IN SYSTEM

would become

	ENTRY. SJ,NXT,,.TXWDW,0,<NEXT JOB BLOCK IN SYSTEM>

o SJ is the name of the BEGSTR.

o NXT the name of the data item.

o The  omitted  third item is in case this table is an offset within an
  outer table. See SLBMAC and ELBMAC.

o .TXWDW is the name of the  routine  to  output  the  value.  Standard
  routines are:

    .TXWDW	XWD octal
    .TDECD	Decimal, followed by "."
    .TOCTW	Octal word
    .TSTCF	CTERM state
    .TCHRS	ASCII word (not a pointer), up to 5 characters
    .TCHR8	8-bit ASCII word (not a pointer), up to 4 characters

  You  can  write others if you want. They are called with the value in
  T1.

o The  0  gives  the  number  of  CRLF's to output after this item when
  DCNSPY is displaying in NOCOMMENT mode. If it's 0 DCNSPY will  output
  4 items per line; set it non-zero to double space or to force an item
  to  be  at  the  beginning  of a line.

o The  comment  is  the  text  which is output in COMMENT mode. This is
  usually just the comment from the BEGSTR macro.

There are SED and EMACS macros to help in changing a BEGSTR macro into one of
these things.


After defining the macro, add the entry

	DOBLK XXX

after the other DOBLK's, where XXX is the XXX in XXXMAC.


SWITCHES:

In  SWTCHS,  Define  a  new  action  command,  and  perhaps  some setup
commands, to implement your new command. Also add some documentation to
the help text at HLPSTR.

Generally an action command just looks like:

	SP	*SJB,0,SPYSJB

o The  asterisk  is a SCAN artifact which I won't explain here. Include
  it on the action commands.

o SJB is the command name

o SPYSJB  is  the  routine which handles the command (described further
  below).

A setup command might look like:

	SP	JOB,SCNJOB,.SWDEC,JOB,FS.NFS!FS.NCM!FS.VRQ

o JOB is the command

o SCNJOB is a variable which gets set to 1 if

o JOB is typed, 0 if NOJOB is typed (-1 if not invoked),

o .SWDEC is the routine which reads the argument (decimal in this case)

o JOB  is  the  list of defaults and ranges to use (defined by the DM's
  just above SWTCHS),

o Then some optional flags:

	NFS	Not a file switch
	NCM	Not a command
	VRQ	Value required (no default)
	LRG	Argument can be larger than 18 bits

ROUTINES:

SPYXXX  is given in the command entry in SWTCHS. It's the routine which
SCAN dispatches to when that command is typed. It is simply:

SPYXXX:	MOVEI T1,TYPXXX		;TYPE OUT THE XXX TABLE
	CALLRET SPYGO

where that's the same old XXX - some name representing your table.

TYPXXX  needs  to  read  in  the  table, output up the header, and call
TYPBLK to output the body of the  table  using  the  XXXMAC  macro.  It
should  first  call  SETXXX  to read the table. Then output the header.
Useful header routines are:

	TYPJOB	Type the job number or special name
	TYPCHL	Output the channel number and skip a line
	TYPTTN	Output the tty number
	TYPTAD	Output the address of the table being output

You can also add your own routines. Finish up with the following:

	MOVE T1,XXXPTR
	CALL TYPBLK
	RETSKP

XXXPTR  is set up along with XXXMAC. TYPBLK outputs the table according
to XXXMAC. The skip  return  indicates  success.  There  are  no  error
returns  now;  the  skip  return  is  just  there  to  waste  time  and
instructions.

(Note:  if  an error occurs while DPYing the table - mainly a NODE JSYS
error - DCNSPY will continue to loop,  continuing  to  get  the  error,
until  the  user types ESC to get back to command level. This is so the
user can see a table which the monitor is setting it up - DCNSPY  would
get  errors  until  the  table were created, and then it would start to
display the table.)

SETXXX:  calls  the  NODE JSYS to read the table. If NODE doesn't know
how to read your table you will have to educate it. It's  the  routine
NDRDB  in  JNTMAN.MAC.  To  call  NODE,  set  up  the  table  name  in
NODARG+.NDBST   and  the  arguments,  if  any,  in  NODARG+.NDBSJ  and
NODARG+.NDBSC. Then do:

	MOVEI T2,NODARG
	NODE
	 ERJMP NODERR		;FAILED - FATAL ERROR

If  NODE  succeeds  the  table is now at NODBLK and the address of the
table is at NODADR.

That's all there is to it.

	SUBTTL HLPSTR - The HELP string

HLPSTR:	ASCIZ ~
DCNSPY uses verb-mode SCAN.  The commands are:

Set-up commands:

  JOB n		Job number to spy on (for SJB, SLB, ELB)
  NRT		Look at NRT's DECnet data (instead of JOB)
  CTERM		Look at CTERM's DECnet data (instead of JOB)
  CHANNEL n	DECnet channel number for that job. Default is 1.
		Channel also controls LAT CBL Circuit numbers, and LAT
		Pending Request Blocks.
  INDEX n	NI PSB or PTB index number. Default is 0.
  CIRCUIT c	Set circuit-id for examining DECnet circuit blocks.
          	(Circuit-ids are of the form DEV-CNT-UNT, (DTE-0-1,CI-0-0.1))
  TTY n		TTY number to spy on (for CTERM's CDB)
  ADDRESS n	Look at the table starting at n, also used for MB msg blk.
		Can also be used for LAT Pending Request Blocks.
  LENGTH l	Set length of the table at ADDRESS n to be l

Action commands:

  AJ		Type out the adjacency Block at the given Address
  CBL		Type out the Circuit Block (LAT) for given Channel = Circuit
  CDB		Type out the CTERM DATA BLOCK for the given TTY
  CI		Type out the CB and PB for DECnet/CI
  DAYTIME	Type out the current time
  ELB		Type out the ELB for the given Job, Channel
  HN		Type out LAT's Host Node Data Block for this system
  MB		Type out the Message Block at the given Address
  MEM		Type out DECnet free pool usage
  MR		Type out the memory request table
  PORT		Type out the Port Table for given Job, Channel
  PRA		Type out a specific LAT Pending Request Block for given Channel
  PRS		Type out the channel/address of all Pending Request Blocks
  PRX		Type out the XMIT buffer associated with a Pending Request
  RCB		Type out Router's RCB for given Circuit-id
  SJB		Type out the SJB for the given Job
  SLB		Type out the SLB for the given Job, Channel
  SLT		Type out the Slot Block for the given TTY
  SPY		Type out the table at the given Address and Length
  TDB		Type out the Terminal Data Block for the given TTY
  PSB		Type out the port storage block for the given index
  PTB		Type out the portal table block for the given index

Cosmetic commands:

  [NO]COMMENT	Type out comments for each field displayed
  [NO]DPY	Use DPY mode
  PAGE		Length by which DPY mode + and - commands shift page
  DELAY		Seconds to sleep in DPY mode

In DPY mode, the Immediate commands are:

  escape	Escape to command mode
  ^Z		Exit to monitor. Type CONTINUE to continue
  ^C		Exit to monitor. Type CONTINUE to continue
  E		Exit to monitor. Type CONTINUE to continue
  C		Toggle the comment/nocomment display mode
  N		Go to Next channel, LAT Circuit, PSB or PTB
  P		Go to Previous channel LAT Circuit, PSB or PTB
  R		Refresh the screen now
  space		Recalculate the screen now
  <CR>		Recalculate the screen now
  +		Move window forward by PAGE lines
  -		Move window backward by PAGE lines

;This and following modules are separate programs so that they can build
;tables based on different universals which contain conflicting symbols.

;All SPYxxx modules search these:
	SEARCH MACSYM,MONSYM
	SEARCH DCNSPY

;The following universals are searched for symbols in the xxxMAC tables:


;And now glue the various subprograms together:
