BREAK (sys)

Purpose:    Sets a check-up for pressing [Ctrl-Break].

Syntax:     BREAK = <ON|OFF>

By default: BREAK=OFF

Parameters:

ON   - sets BREAK = ON. The system checks if the [Ctrl-Break] keys' being
       pressed before executing any DOS command and breaks the execution, if
       those keys are pressed.

OFF  - sets BREAK = OFF. In this case the system controls [Ctrl-Break]
       keys' pressing only during:
       - standard input operations,
       - standard output operations,
       - standard printing operations,
       - operations with standard auxiliary devices (adapters).

     Running the BREAK command without parameters leads to the BREAK current
condition being displayed.
