Entering commands other than RESUME
If you enter a program or subsystem command after pressing Break,
the command interpreter prints the following message on your terminal:
ABORT? (YES/NO). If you respond YES to the message, the command
interpreter aborts the currently suspended program. If you respond
NO to the message, the command interpreter prints the message
COMMAND NOT ALLOWED IN BREAK and prompts you for another command. If
you now enter RESUME, the suspended program resumes at the point
where it was interrupted.
You can enter most commands after pressing Break. Only the commands
that create processes require you to resume or abort the interrupted program.
