Important

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.

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.

Syntax

break=[on|off]
Because the break command has no effect, it is often used to create empty files or delete the content of an existing file. For example:
rem -- cleans the content of the file --
break>log
