/ID = nn
       /INDEX = nn

    Specifies the process to be validated by its index into the
    system's list of software process control blocks (PCBs), or by
    its process identification. You can supply the following values
    for nn:

    o  The process index itself.

    o  A 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 can
       be specified. Any thread-specific data displayed by further
       commands is 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.
