/INDEX=nn

    Specifies the process for which information is to be displayed
    either by its index into the system's list of software process
    control blocks (PCBs), or by its process identification. /ID and
    /INDEX are functionally equivalent. 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. The PID or extended
       PID of any thread of a process with multiple kernel threads
       may be specified. Any thread-specific data displayed by
       further commands will be for the given thread.

    To obtain these values for any given process, issue the SDA
    command SHOW SUMMARY/THREADS. The /ID=nn and /INDEX=nn qualifiers
    can be used interchangeably.
