Specifies the process for which information is to be displayed
    by its index into the system's list of software process control
    blocks (PCBs), or by its process identification (ID). /ID and
    /INDEX can be used interchangeably. You can supply the following
    values for nn:

    o  The process index itself.

    o  The process identification (PID) or extended PID longword,
       from which SDA extracts the correct index. You can specify the
       PID or extended PID of any thread of a process with multiple
       kernel threads. Any thread-specific data displayed by SHOW
       PROCESS will be for the given thread.

    To obtain these values for any given process, issue the SDA
    command SHOW SUMMARY/THREADS.
