Logging out.
===========

You finish a session at the terminal by logging out. Logging out
disassociates the terminal from your project-programmer number.
This means that after logging out, a person at the terminal can
no longer pretend to be you, and cannot access your files in the
way you yourself can.

Logging out also influences accounting, so that your number is
not debited the cost of connection time and computer time any
longer. (The following text presumes that the batch and
spooling system is GALAXY.)

Rationing of the disk memory.
============================

Since the available disk memory is not unlimited, there is a
rationing on disk usage. This means that there is a quota of
disk memory allowed to you.

This quota is much lower after logging out than before. There-
fore, logging out time is a good time for deleting temporarary
files. Even if you did not exceed the logged out quota, you
may still want to delete files at log out time.
%text
The monitor command for logging out is KJOB.
The simplest kind of logout is to type just "KJOB" which means
logout and save all files. This command can be shortened to "K".
If you try to  perform a "KJOB" when you are using more
than your logged-out quota, then the monitor will not allow
you to log out. The monitor will never allow you to log out
until you are below the logged-out quota.

KJOB options
============

If you type only "KJOB", the computer will perform an ordinary
logout. There are however a way to change the behaviour
of the "KJOB" command by adding a slash "/" and a letter
to the end of the command. The addition is called a switch.

KJOB	without switches performs an ordinary logout. Gives
	you some statistics about the job.
KJOB/N	works like KJOB but doesn't give any logout message.
KJOB/C	works like KJOB, but it will not disconnect you from
	the computer if you are using a telephone line. You
	can login again without redialling.
KJOB/H	Gives help information and does NOT log out.
%question q1:
What do you type to perform an ordinary logout WITHOUT getting
any logout message?
%order
%noextra
%right KJOB/n
%right k/n
%wrong kjob
This will log you out, but it will also print a lot of statistics.
%wrong k
%same
%wrong kj
%same
%extra
%lack /n
Use the "N" switch.
%lack K
Use the "KJOB" command.
%wrong /c
This will give you a message.
%wrong /h
"H" is for "HELP"
%lack /
You must have a "/" to separate "KJOB" from "N".
%wrong
Take a look in the list above!
%wrong
%question q2:
Suppose you are not quite sure of how to log out. Which
switch do you use to get some help about it?
%noextra
%right kjob/h
%right k/h
%right /h
%right h
%extra
%lack h
Which letter does "HELP" start with?
%wrong n
The switch "N" will log you out immediately.
%wrong kjobh
You forgot the "/" between "KJOB" and "H".
%wrong KH
%same
%wrong
Write "KJOB", add a "/" and then a certain letter.
%wrong
%question if percent = 100 then
OK. You seem to manage this lesson pretty well. Before
finishing I will only give you one more simple question:

Type four positive integers x, y, z and n, such that n > 2 and

		 n    n    n
		x  + y  = z	.

%neutral
Sorry, I'm afraid you missed this one. But ... even the
sun has spots. Since you answered all the other questions
correctly, I will not report you to your mathematics teacher.

	you some statistics about the job.
KJOB/N	works like KJOB but doesn't give any logout message.
KJOB/C	works like KJOB, but it will not disconnect you from

You have now finished the whole course of twelve lessons.
Thank you for your patience and hard work. I hope you
enjoyed learning to use the DEC 10 in this way.

If you have any comments on the course, such as what was
too difficult or too easy, or some question which should
be rephrased, then please write and tell me.
