Stopping a Command or Program
You may sometimes need to stop a command or program while
it is running. Many application programs provide a command
you can use to cancel or even undo an operation. If you have
entered an MS-DOS command that you want to stop, try one
of the following commands:
Hold down the Ctrl key and press C
Hold down the Ctrl key and press Break.
These methods may also work in your application program. If
you cannot stop a particular operation, however, you may need
to reset the computer, as described in the following section.
C a t i o n
It is best not to turn off the computer to stop a program or
command. If you have created new data that you have not
yet stored, it will be erased if you turn off the computer. The
Apex stores your data in its memory until you save it; but
the memory area is erased each time you turn off or reset the
computer.
Resetting the Computer
Occasionally, you may want to clear the computer’s current
settings or its memory without turning it off. This is called
resetting the computer.
You can reset the computer to reload the operating system. You
may need to do this if an error occurs and the computer does
not respond to anything you enter on the keyboard; you can
reset the computer and try again. However, resetting erases any
data in the computer’s memory that you have not stored; so
reset your computer only if
necessary.
