Break is a command to sets or clears extended CTRL+C checking on MS-DOS systems. If used without parameters, break displays the existing setting value.
If command extensions are enabled and running on the Windows platform, inserting the break command into a batch file enters a hard-coded breakpoint if being debugged by a debugger.
Break command syntax
The syntax of the Break command is as follows:
break=[on|off]

This command is no longer in use. It is included only to preserve compatibility with existing MS-DOS files, but it has no effect at the command line because the functionality is automatic.
