	General Information
	------- -----------

		The Institute's computer is running under the Tenex
	Time-sharing System, which was built around the Dec PDP-10,
	by Bolt Beranek and Newman, Inc. of Massachusetts.  Before
	Tenex, we ran on a Dec 10/50, Series 4 Monitor Timesharing
	System, and we still have many of the Dec programs in active use.
		You will be assigned an identifier, consisting of 
	user's name, password, and account number.  You will use this
	identifier each time you log into the system.


		Whenever you are typing (almost), the rub out
		key will delete the last character you typed.
		In Lisp, <ctrl>-U will delete the whole line you
		are typing and let you start the line over.

		In the following descriptions of commands: 

		<cr> means "press the return key"

		<sp> means "press the space bar"	

		<$>  means "press the enter key"
			(This key is sometimes called alt-mode).

		<ctrl>-C means type C while holding down the control

	How to log into the EXEC
	--- -- --- ---- --- ----

		The EXEC is the main supervisory program under which
	we edit, program, and print.

		Turn on the teletype by pushing the start key.  Then
	type a <ctrl>-C, and the tty will print the login message.
	When the  "@" sign appears      type "LOGIN" or "LOG" <$>
	it will respond with (USER)     type your user name <$>
	the response is (PASSWORD),     type your secret password <$>
	responding with (ACCOUNT #),    type "206 <cr>"	

	It will look like this -
	@ login (USER) 206ab (PASSWORD)      (ACCOUNT #) 206
	(Have you noticed the typing was suppressed on your password?
	That is done to keep your files private.)  A quickie way to
	log in is to type:
	@  "log <sp> 206ab <sp> ab <sp> 206 <cr>"  which will appear as	 
	@ "log 206ab  206".

	How to log out
	--- -- --- ---
		Now that you can log into the system, let's talk
	about logging out, before we go on to other things.  

		LOGOUT closes any file you may have open, and
	clears your JOB from the system.  An example of LOGOUT is:

	@ K  <cr>
	 [CONFIRM]  <cr>
	kILLED JOB 3, USER 206ab, ACCT 1, TTY 10 AT 5/25/73 1447
	USED 0:0:14 IN 3:47:59

	Tenex System Commands
	----- ------ --------

	 Log  in please.   You  are talking  to the main  supervisory
program  called the  EXEC.   Whenever it  is ready  for a  command it
sends you an "@".   You then have  two broad choices: either  request
information from  the system  or run  some kind  of user  program. In
following  section we  have listed the  Tenex commands  you may need.
The full  word  form of  the  command is  listed, with  the  shortest
allowable abbreviation underlined.

		Signaling the System
		--------- --- ------

		<ctrl>-C    You can
			    always get the attention of the system
			    by holding down the CTRL button and
			    typing "C" a couple of times.
			    Your program may be continued with
			    the "CONT" command as
			    if no halt had occurred, assuming you	
			    have not altered your core image (by
			    running some other program, etc.) One
			    <ctrl>-C will return you to the system if
			    your program is waiting for input from the	
			    tty, otherwise two <ctrl>-C commands are	
			    necessary to halt a running program.

		@           The @ typed after a <ctrl>-C indicates that
			    the system is ready for a new command. The
			    system will type an @ upon completion of a

		;	    Typing a ";" causes the rest of a command	
			    line to be considered a comment rather than
			    a command.

		Information Commands
		----------- --------
		?	    A user can type a ? at any point where Tenex
           	-	    appears to expect a keyword or argument, and
			    it will respond with a list of allowable key-
			    words or arguments.  

			    Will allow you to check your program to
			    see if it is progressing. This will not
			    stop your running program, tho it acts 
			    as an interrupt character, which causes
			    a Runstat and Usestat to be typed out.

		DAYTIME <cr>		
		--          Tells you date and time of day.

		DSKSTAT <cr>
		--          Tells you how many pages are now being used.

		JOBSTAT <cr>
		--          Tells you who is logged into this device.

		RUNSTAT <cr>
		----        Used to determine the status of a job that	
			    appears to have stopped running.

		File Manipulation Commands
		---- ------------ --------

		APPEND <filename> <$>
		---	    Adds information in one or more source
			    files to the end of a destination file.
			    The source file remains unaffected.

		---	    Will continue a program interrupted by a
			    Control C.

		COPY <filename> <$>
		---	    Copies one file onto another.  Type the
			    source fileneme first, and the destination
			    filename second.

		DELETE <filename> <cr>
		---	    Eliminates files.  Multiple files can be
			    eliminated by separating the files with a	
			    comma, space, or altmode.  An * can be used 	
			    for universal file names or extensions, but
			    be careful!!  You may undelete files with	
			    undelete. To "really delete" all deleted
			    files, say "expunge".

		---         Tells you information about your directory
                 	    of files.  For examples of what you can do
			    see the sample session that was handed out.

		EXPUNGE <cr>
		---	    Removes permanently deleted files from
			    your directory.

		K <cr> (CONFIRM) <cr>
		-	    Logout

		REENTER <cr>
		---         Will begin program execution at the reentry
			    address, providing the program has been 
			    placed in core first.	

		RENAME <$>  Changes a file name.

		TYPE <filename> <cr>   Will type out the file specified.

		UNDELETE <file name> <cr>
	        ---         Restores a deleted file.

		EDIT <cr>
		--- 	    IMSSS command to load SOS, the editor.
			    See the INTRO you already have for the
			    AI computer for information on how to use



	To enter the editor:
		When the exec types an "@", type EDIT<cr>.
		The editor will type "FILE =", and wait for
		you to type a file name.  After you type the
		file name, press the <enter> key (sometimes
		called <alt-mode>), if you are creatiing a new
		file.  If you are editing an old file, type a
		carriage return after the file name.

	To use the editor:
		See INTRO (for the AI computer) which you were
		given at the beginning of the quarter.  The editor
		is the same.  (It is called SOS).

	To leave the editor:
		When the editor types an "*", type E<cr>.


	To enter Lisp:
		When the exec types an "@", type ILISP<cr>.
		∨hen Lisp types ALLOC (Y OR N) ? type N or <cr>.
		You are now talking to the top level of Lisp, which
		is waiting for you to give it something to eval.
		To read in a file with function definitions on it,
		type (DSKIN FILNAM), where FILNAM is the name of
		the file.  If the filename has an extension,
		e.g. FILNAM.EXT, type (DSKIN (FILNAM . EXT)).
		It will type the names of the functions that it
		finds in the file--if there are errors in the file
		it may not find all of the functions.

	When Lisp  finds an error,   it will  type an  error message.
Then instead  of typing an "*", it will type  "1:",  and wait for you
to type something. This is  the break package. There are many  things
you can do here, described in the  UCI Lisp manual.  If you just want
to  get back  to  the top  level of  Lisp, type  two up  arrows (↑↑),
followed by a <cr>. (Up  arrow is <shift>-N).  If you never  want the
break package  you can type (*RSET  NIL) when you enter  Lisp to turn
it off.

	When you are in Lisp, you can print out readable copies of
function definitions with the function GRINDEF.  For example, to list
the function UNION, type (GRINDEF UNION).  When you turn in computer
homework, please include GRINDEF listings of all of your functions.

	To leave Lisp type <ctrl>-C or (EXIT).

	There is a UCI lisp manual on a shelf in teletype room 31.  To
use UCI lisp, you also need a Lisp 1.6 manual.  You can buy both of
these manuals in room 101 Polya.

	Filenames consist  of  a name,  an extension,  and a  version
number,  written for, example,  FILNAM.EXT;1.  The  name should never
be more than 6 characters, and  the extension should be no more  than
3 characters.   The extension  can be  omitted entirely.   When using
Lisp  and the editor,  there is no  way to specify  a version number.
They always  use the  most recent version.   When  using the  editor,
just type FILNAM.EXT, or if  there is no extension, just FILNAM.  For
using Lisp  see above.    For exec  commands,  such as  deleting  and
copying, you can specify the version number.
	Whenever  you log  off,  please use  the  EXPUNGE command  to
really  get rid of  deleted files.   Even if you  haven't deleted any
files, the editor may  have deleted some  old versions of your  files
which you should EXPUNGE.

	There are many more things you can do with the system.  If you
have any questions, please ask me.  I will be in room 11 in Ventura
as often as possible during the next couple of weeks--especially between
1:00 and 2:00 on Monday, Wednesday, and Friday.
