ABOUT TOPS
----------

  TOPS IS AN OPERATING SYSTEM FOR DEC-
20 AND DEC-10 COMPUTERS. TOPS IS SOME-
THING OF A 'MEMORY HOG' AND EATS UP A
LOT OF CORE. THE SYSTEM IS VERY USER
FRIENDLY AND IS THUS GOOD FOR SCHOOLS
BUT DUE TO ITS EXCESSIVE OCCUPATION OF
MEMMORY IT IS NOT OFTEN USED BY BUIS-
NESSES, WHO SEEM HAPPIER WITH RSTS 
(ANOTHER DEC OPERATING SYSTEM WHICH 
CAN SOON BE READ ABOUT IN MY UPCOMING
PHILE: HACKING RSTS).

RECOGNIZING A TOPS
------------------

  THE TOPS IS ONE OF THE EASIEST SYS-
TEMS TO RECOGNIZE, PARTLY BECAUSE OF 
ITS UNLIKELY PROMPT '@' BUT MOSTLY BE-
CAUSE TOPS IDENTIFIES ITSELF QUITE 
OPENLY. A TYPICAL TOPS MIGHT LOOK LIKE
THIS WHEN YOU FIRST CALL AND GET SYSTEM
ATTENTION (WITH <RET> OR ^C):

 DEC-20/60 CAMPUS COMPUTER, TOPS-20 MONITOR 5.1(6101)
@

LOGGING ON
----------

  TO LOG ON TO A TOPS:
1. TYPE THE WORD 'LOGIN' OR JUST 'LOG'
2. A SPACE
3. A LOG-ON ID
4. A SPACE
5. YOUR PASSWORD

THE LOG-ON ID CONSISTS OF THREE LETTERS
THAT DESIGNATE A USER-GROUP, A PERIOD
AND A USERNAME. EXAMPLE: ABC.GALACTUS
THE PASSWORD DOES NOT ECHO BACK SO YOU
WILL NOT SEE IT AS IT IS TYPED, IT CAN
CONSIST OF AS MUCH AS EIGHT BYTES, 
HOWEVER IVE SEEN ONE MAJOR SCHOOLS 
SYSTEM THAT ONLY USED THREE. A VALID 
LOG-ON MIGHT LOOK LIKE THIS:


@LOG ABC.GALACTUS
 JOB 13 ON TTY10 22-APR-87 13:18:19, LAST LOGIN 22-APR-87 13:06:40
@
 
WHAT YOU CAN DO
---------------

  ONE OF THE WONDERFULL THINGS ABOUT 
TOPS IS THAT MOST TOPS WILL ALLOW YOU
TO DO LOTS OF THINGS WITHOUT EVEN LOG-
GING IN. MOST SYSTEMS WILL ALLOW YOU
TO VIEW HELP FILES WITHOUT LOGGING IN.
YOU CAN DO THIS BY TYPING HELP FOR 
OVER-ALL HELP, HELP ? FOR A LIST OF
AVAILABLE HELP FILES. SOME OF THE BEST
HELP FILES TO VIEW ARE HELP LOGIN AND
HELP COMMANDS. OF COURCE THE SYNTAX IS

@HELP <HELP FILE NAME>

  ANOTHER IMPORTANT COMMAND THAT IS 
USUALLY AVAILABLE TO YOU IS 'SYSTAT'
OR JUST 'SYS'. THIS COMMAND WILL GIVE
YOU A LIST OF ALL USERS CURRENTLY ON 
THE SYSTEM, ALONG WITH THEIR TTY#, 
JOB#, AND LOGIN ID. A TYPICAL SYSTAT
MIGHT LOOK LIKE THIS:


@SYSTAT
 WED 22-APR-87 11:52:18  UP 2:56:28
 16+5 JOBS   LOAD AV (CLASS 0)   3.86   3.29   3.38

   3   222  IBMSPL  OPERATOR
   4   223  OPR     OPERATOR
   5    54  JOBMON  OPERATOR
@

  ANOTHER GOOD COMMAND THAT MAY BE AV-
AILABLE TO YOU IS THE 'WHO IS' OR JUST
'WHO' COMMAND. IT WILL GIVE YOU ADDED
DETAILS ON A GIVEN USER AS REFERENCED
BY JOB# TTY# OR LOGIN ID. 
  WHAT YOU WANT TO DO TO ACCESS A TOPS
IS CALL UP AND DO SEVERAL SYSTAT'S IN
HIGH USAGE PERIODS. YOU WANT TO GAIN  
ABOUT 100 LOGIN ID'S IN THIS MANNER.
THEN YOU NEED TO TYPE THEM UP INTO A
FILE. NEXT CREATE A FILE OF LIKELY 
PASSWORD (THINK LIKE A USER... FOR 
INSTANCE... COLLAGE STUDENT PASSWORDS
MIGHT BE NAMES OF POPULAR ROCK GROUPS)
HELP LOGIN WILL USUALLY TELL YOU HOW
MANY BYTES ARE IN THE PASSWORDS... MOST
SYSTEMS I HAVE FOUND USE EIGHT. IN THAT
CASE GOOD PASSWORDS MIGHT BE COMPUTER
WARGAMES OR MADDONNA. ANYWAY CREATE
A FILE OF ABOUT 100 OF THESE. THEN
WRITE A PASSWORD HACKING PROGRAM THAT
LOADS THEM INTO TWO ARRAYS AND TRIES 
ALL POSSIBLE COMBONATIONS. THIS IS 100
* 100 =10,000 ATTEMPTS. THIS IS BOUND
TO GAIN YOU ACCESS. 

AFTER YOUR IN
-------------

  THE FOLLOWING IS AN EXPLANATION OF
TOPS COMMANDS THAT YOU WILL BE ABLE TO
ACCESS ONCE YOU ARE IN. (VARIOUS VER-
SIONS OF TOPS DIFFER BUT THE FOLLOWING
ARE COMMON COMMANDS THAT YOU WILL FIND
USEFULL)

                              ADVISE HELP

     THE ADVISE COMMAND LINKS YOUR TERMINAL WITH ANOTHER USER'S TERMINAL
     SO THAT YOU CAN GIVE COMMANDS TO THAT USER'S JOB.  THE ADVISEE  CAN
     STILL GIVE COMMANDS  TO THE JOB.   [NOTE: FOR ADVISE  TO WORK,  THE
     ADVISEE MUST HAVE ISSUED THE  RECEIVE ADVISE COMMAND.  THE LINK  IS
     PREVENTED BY DEFAULT OR BY TYPING REFUSE ADVISE.]

     THE GENERAL FORM OF THE COMMAND  IS

        ADVISE USER

     WHERE "USER" IS EITHER A USER NAME OR A TERMINAL LINE NUMBER.

     WHILE THE ADVISE COMMAND IS IN EFFECT, THE COMMANDS YOU GIVE AFFECT
     THE ADVISEE'S JOB  INSTEAD OF YOUR  OWN.  TO END  AN ADVISING  LINK
     THAT YOU HAVE MADE BETWEEN  TERMINALS, YOU MUST TYPE CTRL-E,  WHICH
     IS NOT ECHOED ON EITHER TERMINAL.

     USE THE  CONTROL-^?   (CONTROL  UP-ARROW QUESTION  MARK)  FOR  HELP
     DURING ADVISE.   FOR  MORE  INFORMATION, SEE  THE  TOPS-20  COMMAND
     REFERENCE MANUAL AND THE RELATED TOPIC OF TALK.
@

                               TALK HELP

     THE TALK COMMAND  LINKS YOUR TERMINAL  TO ANOTHER USER'S  TERMINAL.
     TYPE 'TALK ARGUMENT' WHERE  "ARGUMENT" IS EITHER  A USER-NAME OR  A
     TERMINAL'S LINE  NUMBER.  AS  SOON AS  YOU GIVE  A SUCCESSFUL  TALK
     COMMAND, BOTH TERMINALS BEGIN PRINTING  BOTH USERS' TYPING AS  WELL
     AS SYSTEM RESPONSES  TO THAT  INPUT.  EACH  JOB, HOWEVER,  RECEIVES
     INPUT ONLY FROM ITS OWN TERMINAL.

     MESSAGES SENT  BETWEEN TERMINALS  MAY  BE PRECEDED  BY ONE  OF  THE
     FOLLOWING:
       ;      TREAT ALL TEXT UP TO END OF LINE AS A MESSAGE.
       !      TREAT ALL TEXT UP TO THE NEXT "!" (WHICH MUST BE ON THE SA
ME
              LINE) AS A MESSAGE.  THIS FEATURE ALLOWS YOU TO PUT A MESS
AGE ON
              THE SAME LINE AS A COMMAND.
       REMARK REGARD ALL INPUT, UP TO A CTRL-Z, AS A MESSAGE, REGARDLESS
 OF
              INPUT BY THE OTHER USER.

     YOU CANNOT USE  TALK TO  CONTACT A USER  WHOSE TERMINAL  IS SET  TO
     REFUSE LINKS.  TYPE CTRL-C, AND USE MAIL TO SEND MAIL INSTEAD.

     FOR MORE INFORMATION, REFER TO THE TOPS-20 COMMAND REFERENCE MANUAL
     OR THE DOCUMENT HLP:TALK.DOC.  RELATED HELP TOPICS REFUSE,  REMARK,
     AND RECEIVE.
@

                              DEPOSIT HELP

     THE DEPOSIT COMMAND CHANGES THE CONTENTS OF A MEMORY LOCATION.  THE
     SYNTAX IS:

        DEPOSIT LOCATION CONTENTS

     WHERE "LOCATION"  IS THE  OCTAL ADDRESS  OF A  MEMORY LOCATION  AND
     "CONTENTS" IS AN OCTAL NUMBER TO BE DEPOSITED AT THAT ADDRESS.

     DEPOSIT CHANGES ONE  MEMORY LOCATION  AND LEAVES  YOUR TERMINAL  AT
     TOPS-20 COMMAND LEVEL.

     RELATED COMMANDS: DDT, EXAMINE,  FORK, SET PAGE-ACCESS.  SEE  ALSO:
     "TOPS-20 COMMAND REFERENCE MANUAL".
@

                             DIRECTORY HELP

     THE DIRECTORY  COMMAND LISTS  THE  NAMES OF  FILES IN  A  SPECIFIED
     DIRECTORY.  ITS SYNTAX IS:

        DIRECTORY <DIRECTORY>NAME.TYPE,
        SUBCOMMAND

     IF YOU OMIT <DIRECTORY>, YOUR DIRECTORY IS SEARCHED.  TO GIVE  MORE
     THAN ONE  FILENAME, SEPARATE  THEM  WITH COMMAS.   IF YOU  GIVE  NO
     FILENAMES, DIRECTORY WILL  LIST ALL  THE FILES  IN THAT  DIRECTORY.
     YOU MAY USE WILDCARD CHARACTERS (*  AND %) WHEN TYPING FILE  NAMES.
     IF YOU TYPE A COMMA AT THE  END OF THE LINE, JUST BEFORE YOU  PRESS
     RETURN, YOU WILL BE PROMPTED (WITH @@) FOR SUBCOMMANDS.

     FOR MORE INFORMATION, SEE THE TOPS-20 COMMAND REFERENCE MANUAL  AND
     THE  RELATED   TOPICS   OF  FDIRECTORY,   TDIRECTORY,   VDIRECTORY,
     SUBCOMMANDS, WILDCARDS, AND DOCUMENTS DIRECTORY-PROTECTION.DOC  AND
     DIRECTORY-SUBCOMMANDS.DOC IN THE HELP DIRECTORY (LOGICAL HLP:).
@

                              EXAMINE HELP

     EXAMINE DISPLAYS, IN OCTAL, THE CONTENTS OF A MEMORY LOCATION WHOSE
     OCTAL ADDRESS YOU SPECIFY.  THE SYNTAX IS:

        EXAMINE ADDRESS

     THE CONTENTS  WILL  BE  DISPLAYED  AS  TWO  6-DIGIT  OCTAL  NUMBERS
     SEPARATED BY A PAIR OF COMMAS  (,,).  THE TWO NUMBERS ARE THE  LEFT
     AND RIGHT HALVES  OF THE 36-BIT  WORD.  IF THE  LEFT HALF IS  ZERO,
     ONLY THE RIGHT HALF IS DISPLAYED, WITHOUT THE COMMAS.

     RELATED COMMANDS: DDT, DEPOSIT.  SEE ALSO: HELP DDT, HELP  DEPOSIT,
     "TOPS-20 COMMANDS REFERENCE MANUAL".
@


                              EXECUTE HELP

     THE EXECUTE  COMMAND COMPILES  SPECIFIED FILES  (IF NEEDED),  LOADS
     THEM INTO  MEMORY,  THEN  BEGINS EXECUTION  OF  THE  PROGRAM.   THE
     COMMAND HAS THE FORM:

        EXECUTE /SWITCH SOURCE/SWITCH OBJECT,...

     WHERE SOURCE IS THE  NAME OF THE SOURCE  PROGRAM AND OBJECT IS  THE
     NAME OF THE RELOCATABLE BINARY FILE.  IF "OBJECT" IS NOT SPECIFIED,
     THE OBJECT FILE  WILL KEEP THE  NAME OF THE  SOURCE FILE WITH  FILE
     TYPE  REL.   THE  FILENAMES  OF  THESE  FILES  ARE  RESTRICTED   TO
     6-CHARACTER NAMES AND 3-CHARACTER TYPES.

     IF SWITCHES  ARE PLACED  BEFORE ALL  FILES IN  THE COMMAND  (GLOBAL
     SWITCHES), THEY ACT AS DEFAULTS FOR ALL; OTHERWISE THEY AFFECT ONLY
     THE FILE WHOSE NAME IMMEDIATELY PRECEDES THE SWITCH.  FOR A LIST OF
     AVAILABLE SWITCHES, SEE HLP:LOAD-CLASS-SWITCHES.DOC.

     FOR MORE INFORMATION, SEE THE TOPS-20 COMMAND REFERENCE MANUAL  AND
     THE RELATED TOPICS OF COMPILE, DEBUG, LOAD, AND RUN.
@

IN ADDITION MOST STSTEMS HAVE AN E-MAIL
SYSTEM OF SOME SORT AND VARIOUS LANGUAG-
ES WHICH CAN BE ACCESSED SIMPLY BY 
TYPING THE LANGUAGE NAME, SUCH AS 
BASIC, FORTRAN, COBOL AND PASCAL
