Break Mode

When a process is in control, it reads user input and acts according to its own rules and conventions. It is possible to temporarily interrupt the process to go back to the command interpreter (CI) without exiting the process and having to restart it. When this occurs, the CI is executing in break mode.

Activating the BREAK key interrupts the data communication function of the terminal. This can suspend or terminate the process currently executing (for example, a subsystem or user program). The program currently running is interrupted, not the actual MPE/iX command that started execution of the program; this command may have already completed execution. In break mode, you can enter MPE/iX commands and user-defined commands (UDCs). When you press the BREAK key, the colon prompt (:) appears, indicating that your session is in break mode.

The following MPE/iX commands can be interrupted by pressing the BREAK key. This action aborts the output of the command, not its action:

   :BYE

   :HELLO

   :HELP

   :LISTF

   :LISTVS

   :REDO

   :REMOTE HELLO

   :REPORT

   :SHOWDEV

   :SHOWIN

   :SHOWJCW

   :SHOWJOB

   :SHOWME

   :SHOWOUT

   :STREAM

The following MPE/iX commands can by interrupted by pressing the BREAK key. This action temporarily suspends execution of the command; execution can be resumed by entering :RESUME.
