 	SET CPU cpu_id

     Selects a CPU to become the new "SDA current CPU".  The CPU is
     specified by its hexadecimal CPU ID, a value between 00 and 1F.
     SET CPU also changes SDA process context.  The new "SDA current
     process" is the current process on the specified CPU.  If there
     is no current process on the new "SDA current CPU", then the
     "SDA current process" is undefined, and no process context
     information will be available until SDA process context is set
     to a specific process.

     Subsequent SDA commands display information based on both the new
     "SDA current process" and new "SDA current CPU".

     Type HELP PROCESS_CONTEXT for specific information about the
     "SDA current process".  Type HELP CPU_CONTEXT for specific
     information about the "SDA current CPU".

     Note:   SET CPU is only valid when analyzing a crash dump.  It is not
             a valid command when analyzing the running system, because
             all the CPU-specific information may not be available.
