If you are executing your command processor, and it has begun to terminate abnormally, you receive a diagnostic message at the terminal followed by a READY message. You then have a choice of terminating your program or testing it. If you issue the TEST command without operands, the TEST command processor receives control and you can use the TEST subcommands to test your program. If your response is anything but TEST, a question mark (?) or TIME, your command processor is abnormally terminated.
