The break command may be used to enable or disable the breaking capability of the computer. For example, if you wanted to cancel a batch file or another MS-DOS processes, you can press Ctrl+C for a prompt asking if you want to cancel the current process.
Turning break off will cancel Ctrl+C; however, the user can still press Ctrl+Pause/break and have the capability of getting out of a batch file or current running process.
break on
Turns on the break, which allows the Ctrl+C function.
break off
