HOW TO USE RSTS/E INFO
INFO is a program for reading on-line documentation. It's
chief value lies in it's "Tree Structure" which allows the
user to quickly obtain information at various levels of
detail.
Below is a diagram of how the information is organized in
INFO. Keep in mind that each of the small boxes is called a
"node".
_________
|DIR
|
The DIRECTORY node

|
"D" shows you this node.

SUBTOPIC nodes:
These give more
specific detail
There are several types of INFO commands. The two most
commonly used commands are "M" and "U". If you notice in the
picture, DIR is at the very top of the INFO tree. when you
run INFO, you will see something called a menu. Page two
shows the Menu belonging to the DIR node.
To obtain information on, or "select", any item in the
menu, just press the "M" key on the keyboard. Info will print
the words "Menu Item:", which is its way of asking for you to
type in the name of one of the menu items. Once you have
typed it in, INFO will show you that subject. To go back up
the tree to the menu again, type the letter "U", which is the
"UP command.

Some topics (or "nodes") are too big to fit on the
screen. If the number in the lower right corner of the screen
is not "100", then there is more to be seen than is on the
screen. To show the next screenful, just type a space. To
reread the last screenful, type a backspace.
To quit INFO, just type a "Q". INFO will ask
really want to quit and you can answer Yes or No.

Use the following guide if you are not on a campus Teleray 10.
Dialup Telerays:
"SET TELERAY"
"RUN [44,12]INFO"
Heath H19:
"SET VT52"
"RUN [44,12]INFO"
Hewlett Packard:
"MU INFO[44,12]/HP"

USER FEEDBACK
INFO is being made available on a test basis. Comments
are
desired,
and
in
fact encouraged. If you have any problems using the
program,
find any bugs, or want to make any suggestions for
improvements or
changes, you can use the BUG program, which automatically
updates a
comment file which is read regularly.
Feel free to create your own INFO nodes. Instructions for doing
this
are contained within INFO. (Look in the node called "INFO".)
If
you
create
documentation
that
you
think
might be of
general
interest to other users, you can use the BUG program to tell me
where
it is, and it might find it's way into the public INFO tree.
TO RUN THE BUG PROGRAM, do:
MUN [44,12] BUG INFO<cr>
then
type your message. Finish with control-Z (that is hold
down the
key marked "Control" and press Z simultaneously.
To read other messages, use the REPLY program, as follows:
RUN [44,22]REPLY
