APPENDIX B
THE CONTROL CHARACTERS
Your terminal keyboard allows you to type control characters which perform special
functions. A control character is the signal transmitted to the computer when you hold
down the
CTRL
key and press another key at the same time. The following list contains
the most important control characters. The
AMOS User’s Guide contains a complete list
of control characters and their functions.
Control-C Control-C is the system interrupt command. You use it to interrupt
whatever program is in progress and return to AMOS command level.
After pressing
CTRL
/
C
to interrupt a program, you cannot resume
execution of that program; you must start it over from the beginning.
Some programs, such as AlphaVUE, do not recognize a Control-C as an
exit command; instead you must use the exit command for that program
if you want to return to AMOS command level.
Other programs do recognize a Control-C; however, if an exit command
exists for a program, it is usually better to use that command than to
press
CTRL
/
C
. Many programs perform various closing functions when
you use their normal exit commands and would not have a chance to
perform those procedures for an orderly exit if you bypass them by using
a Control-C.
Control-U At AMOS command level, you may move the leftmost character of the
command line you are typing by pressing
CTRL
/
U
.
Control-S A program or command often displays more data on your terminal than
fits on one screen. To stop the screen display, press
CTRL
/
S
.
You can now read the data on the screen at your leisure. Not only does
the display freeze, but AMOS actually stops sending data to your
terminal until you press
CTRL
/
Q
(see below); at that point, AMOS
resumes sending information where it left off.
While a Control-S is in effect, AMOS stores, but does not act upon,
anything you type except for
CTRL
/
Q
. There is, however, a limit to how
