Key Description
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 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.

Correcting Typing Mistakes
You can correct any mistakes you may make while typing a command line as long as you have not yet
pressed the
ENTER
key. You can:
Press
RUBOUT
to erase single characters.
Type
CTRL
/
U
to move the cursor to the beginning of the line.
Type
CTRL
/
C
to tell AMOS to ignore the line.
See the table above for explanations of
RUBOUT
and control characters.
If you press the
ENTER
key before correcting your mistake, and the command you entered was not a valid
AMOS command, AMOS lets you know it did not understand the command. For example:
PRIMT
ENTER
?PRIMT?
(You meant to say PRINT.) After letting you know it does not understand the command, AMOS displays
its prompt symbol. You can now try again.
If the AMOS line editor is enabled, you can recall a previous line to the screen by typing
CTRL
/
R
. In
the sample conversation above, press
CTRL
/
R
at the AMOS prompt to recall the line
PRIMT
to the
screen. Use the
key to move back to the “M” without erasing characters, then type an “N” to overwrite
the “M.” Press the
ENTER
key to enter the command again.
Your particular terminal or workstation undoubtedly has many features we haven't covered in this
section. For complete information on using your terminal or workstation, refer to the owner's manual that
accompanied it.
