THE TERMINAL KEYBOARD
The first step in communicating with AMOS is to be able to type your instructions on the
terminal keyboard. The keyboard is very similar to a standard typewriter’s, but it has a
few extra keys with special functions.
Take a moment to look at your keyboard so you can easily locate these keys later:
KEY DESCRIPTION
RETURN RETURN
(sometimes labeled
ENTER
or with an arrow that curves to the left) is the
carriage return key. Just as you press the carriage return on a typewriter to
begin a new line on the page, a
RETURN
tells the computer you are ending a line of
input and you want to begin a new line.
The computer does not normally process an instruction from you until you
press
RETURN
to let it know you are finished with that line.
RUBOUT RUBOUT
is the deletion key; it backspaces AND deletes. It may be labeled
RUB
or
DEL
.
If you make a mistake while typing an instruction to AMOS, you can erase it
using the
RUBOUT
key.
SHIFT
The
SHIFT
key on most keyboards acts much like the shift key on a typewriter.
By holding down
SHIFT
, you can type upper case letters and the symbols on the
upper half of the keys with two symbols.
CAPS
LOCK
While the CAPS LOCK key is enabled, letters you type appear in upper case.
Keys other than letters are not affected by the CAPS LOCK key on most
keyboards.
ESC
This key may be labeled ESCAPE or ALT MODE. It is used with several
application programs (such as AlphaVUE) to signal the end of input, or to
switch between command modes; however, you do not use
ESC
at AMOS
command level.
CTRL
Use the
CTRL
(or CONTROL) key with other keys to enter a different kind of
character—a "control character." AMOS and much of the software on the
computer interpret control characters as special instructions.
To type a control character, hold down the
CTRL
key and press the other key.
For example, to type a Control-C, hold down the
CTRL
key and type the letter C.
In this book, we indicate control characters this way:
CTRL
/
C
. Appendix B
lists some of the control characters AMOS recognizes.
