break命令可用于启用或禁用计算机的break能力。
例如，如果要取消一个批处理文件或另一个MS-DOS进程，可以按Ctrl+C得到一个提示，询问是否要取消当前进程。
关闭break将取消Ctrl+C;
然而，用户仍然可以按下Ctrl+Pause/break键，并有能力获得批处理文件或当前运行的进程。
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.
更新版本的Windows (Windows ME, Windows 2000, Windows XP，以及更高版本只包含了这个命令来进行向后兼容性，关闭break没有任何效果。
Newer versions of Windows (Windows ME, Windows 2000, Windows XP, and higher) only include this command for backward compatibility and turning the break off has no effect.
