Stopping a Command or Program
You may sometimes need to stop a command or program while
it is running. Many 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 not, you may need to reset the computer as described below.
Caution
It is best not to turn off the computer to stop a program or
command. If you created new data and have not yet stored it,
the data will be erased if you turn off the computer. The
computer stores your data in its memory area (RAM) until
you save it; but the data 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. You can do this by
resetting the computer.
For example, if an error occurs and the computer does not
respond to your keyboard entries, you can reset it to reload
MS-DOS and try again. However, resetting erases any data in
memory that you have not saved; so reset only if necessary.
