BREAK + Checking Whether Break Was Invoked
     Controls circumstances under which DOS checks for the Ctrl-C 
or Break key (Ctrl-Break on the IBM PC) while programs are 
executing.
    VERSION
          PC-DOS 2.0+
	  MS-DOS equivalent: BREAK (2.0+)
    TYPE
          Internal
    SYNTAX
	  BREAK [ON|OFF]
    OPTIONS
          ON             Sets BREAK to on. BREAK ON allows 
                         interruption of programs while they are 
                         not performing input or output to the 
                         console, the printer, or auxiliary 
                         devices.
          OFF            Sets BREAK to off (the default).
    EXAMPLES
	  CBREAK ON
sets BREAK to ON. To see the status of the command, issue it with 
no argument:
	  ABREAK
	  BREAK is on
    NOTE
     With BREAK set to OFF, DOS checks only when it performs a 
screen or keyboard system call or carries out a printer or other 
auxiliary device operation. Specifying ON instructs DOS to check 
to see whether the Break key combination has been pressed before 
it performs any system call. You can specify BREAK = ON in your 
configuration file.
