halt (or stop)
The
halt
(or
stop
) command stops program execution on a CPU that is running a booted
program. The syntax is:
halt
(or
stop
) 00 (
where
00
is the designated processor number
)
The
processor number
is the designated CPU number displayed by the
show cpu
command.

continue
The
continue
command resumes program execution on the specified processor or on the
primary processor if none is specified. The processor begins executing instructions at the
address that is currently in the program counter (PC). The processor is not initialized.
The
continue
command is valid only if you have not disturbed the system state and if you
halted the system by pressing the halt/reset button on the control panel (Jumper J22 pins 13-
14 must not be installed for the halt/reset button to operate as a halt a button.) or, for
OpenVMS
systems only, by entering Ctrl/P on the console terminal.
