Break
CONTROL-C checking
Break
Purpose:
Sets CONTROL-C check
Syntax:
break [ON]
or
break [OFF]
Comments:
Depending on the program you are running, you may use
COj'lTROL-C to stop an activity (for example, to stop sorting a file).
Normally,
MS-DOS checks to see whether you press CONTROL-C
while it is reading from the keyboard or writing to the screen or
printer_ If you set break to ON, you extend CONTROL-C checking
to
other functions such as disk reads. and writes_
Examples:
To check for CONTROL-C only during screen, keyboard, and printer
reads and writes, type the following:
break off
To find out how break is currently set, type the break command
and press the RETURN key_
Note Some programs may set themselves to respond to
CONTROL-C at any time_ Setting break does not affect these
programs_
