Privilege Class: G
Use BEGIN to resume command execution in a virtual configuration.
CPU ALL
specifies all virtual processors currently defined.
CPU cpuaddr
terminates a hard stop for the specified processors without affecting any others.
CPU cpuaddr1-cpuaddr2
specifies a nonwrapping pair of addresses separated by a hyphen (-) and not
separated by any blanks.
CPU cpuaddr cpuaddr
identifies a list of addresses delimited by blanks, a range of addresses delimited
by blanks, or both.
hexloc
identifies the hexadecimal storage location where execution is to begin for the
processor on which the command is issued. Command execution terminates a
hard stop. To begin multiple processors at specified hexadecimal locations, use
the CPU command with the BEGIN command.
If your virtual machine is in z/Architecture mode, up to 16 hexadecimal digits
are valid. An underscore is permitted to separate the hex digits into two groups
for easier reading if the location is larger than 8 digits, for example:
39A40B_AF8216CE
* terminates hard stop for the processor on which it is issued. No other virtual
processors are affected.
1. If you enter BEGIN without operands, it terminates a soft stop on all virtual
processors in your configuration. If all of your processors are in hard stop,
BEGIN terminates hard stop for the processor on which it is executed.
BEGIN
2. If you enter BEGIN without a starting storage location, command execution
begins at the location the current PSW points to. Unless the PSW was altered
