There is a manual for this course. The manual contains all instructive
texts within the course. You can take the course without the manual,
but it is better to get it, especially if you are using a display
terminal. The filename of the manual is "TOPS.MAN". Ask your computing
center how to get a copy of it.
%text
%ifend qz
When starting to use the DEC 10, you must first get connected to the
computer. Since this is done in different ways for different kinds
of terminals, I do not describe the procedure here. You can check
that you really are connected to the computer by pushing the
"RETURN" key on your terminal. If the computer responds with a "."
in the first column of a new line, then you are connected.
%text monitor:
When you first get connected to the computer you are
communicating with a program called the MONITOR.
The monitor supervises everything that goes on
inside the computer. It will also interpret commands
that you type on your terminal. It is the monitor that
types the "." at the beginning of the line, saying:
"Here I am, at your service!"

%QUESTION T1Q1:
Which key can you push to check that you are in connection to the
computer?

%wrong "
%algol qmsg;
%wrong %
If you want to use the "%" command to stop, back or skip, then you
must write only the character "%" and nothing else. The computer
does not recognize what you write as a "%" command if the computer
receives more than one character from you.
%wrong .
You pushed the dot (".") key instead of the RETURN key.
%WRONG
%WRONG
%GOTO T1
%TEXT T2:
When you are connected to the monitor, you can try some simple
commands. You can for example try the "DAY" command by typing
the word "DAY" followed by typing the "RETURN" key. The computer
will then answer with the date and the time.

Please note that just now you are communicating with
the lesson, you are NOT communicating with
the monitor. You can try out the "DAY" command only
if you first leave this lesson. Therefore wait until
the end of the lesson before you try it.

%WRONG day
You cannot try the "DAY" command now, since you are communicating

you have exited from the lesson. You know that you are communicating with
the monitor if the computer writes a "." in column 1.
%wrong .
A period (dot) is typed by the monitor. It means that the
monitor is ready to accept a command from you.
%WRONG
Which was the last key that you should push after having typed in
the word "DAY"?
%WRONG
You push the "RETURN" key to get the computer to respond.
%GOTO NEXT
%TEXT T3:
The delete key for correcting typing errors.
===========================================

When you are typing information to the computer, you may some
times make a typing error. But the computer will usually not
do what you tell it until you push the "RETURN" key.
If you become aware of your error before pushing
the "RETURN" key, then you can immediately correct it,.
To do that, you push the "DELETE" key on your terminal.
On some terminals, that key is marked "DEL" or "RUB OUT".
Say that you wanted to type "SWEDEN" and by mistake you
typed "SWD". You then push the "DELETE" key to remove the
erroneous "D", and then you continue with "EDEN".

%QUESTION T3Q1:
Try this out by typing "SWD" then pushing "DELETE" and then
typing "EDEN". Finally, as always, end your message to the
computer by pushing the "RETURN" key.
%NOEXTRA
%RIGHT SWEDEN
%wrong SVEDEN
The second letter in "SWEDEN" is "W" and not "V".

%alg qmsg;
%wrong _
Your answer contained the character "_". Perhaps you mistook this
character for the delete key? Look for a button labelled
"DELETE" or "RUB OUT" or something like that, and use upper shift
if this is required.
%wrong delet
You should not type the word "DELETE" but push the single button
labelled "DELETE" or "RUB OUT" or something like that on your
terminal.
%wrong do n t know

%TEXT T4:
You can delete as many characters as you wish as long as
you stay within the line. Therefore, if you have written "SWDEN" and
want to correct your error, you push the "DELETE" key three times to
delete succesively N, E, and D. Now, only "SW" is left
in the memory of the computer, and you can continue with "EDEN".

%QUESTION T4Q1:
Try that out by first typing "SWDEN", then deleting three times
and then typing "EDEN".

Programs are stored on disk areas. When you have a number and
password, you have your own disk area, identified by the
computer by the number.  The SYSTEM also has an area of disk
space, and this is accessable by all users of the computer.

If a program is stored on your own disk area you can run that
program by giving the command "RUN name.ext" where name is the
name you give your program, and ext is the extension of the
program. If you have created a program called "FRED.SAV"
then the monitor command "RUN FRED.SAV" will start to obey
the instructions given in the program "FRED.SAV".

If a program is stored on the system area, and is available to
all users, the command to run that program is "R name.ext".
To run the system program "LISP" you would type:
                R LISP
and the commands in that program would be obeyed.

When the computer types a dot(".") in column 1, then you know

the "DAY" command.

First only the finishing off of this lesson.

%if qz
If you want to get to monitor level and try the "DAY" command,
then you must answer "STOP" when the lesson master program asks
you which lesson you want to take next. This will detach you
from the lessons and put you in monitor level. When you get
the monitor "." type "DAY" (without the quotes!). To get back
to the lessons after this, you must "LOGIN" as shown on the
instruction sheet you received for the "TOPSTEACH" lessons.
