BACKSPACE Key

From time to time, you may make a typing error. This is not
usually a problem if you correct the error before you ENTER
the command. You can use the BACKSPACE key for this
purpose.
Note
Occasionally, you might happen to enter the wrong
command by mistake. If this incorrect command will result
in the loss of data, MS-DOS will usually warn you, and
give you a change to change your mind.
