1    /ADDRESS

       /ADDRESS = pcb-address

    Specifies the process control block (PCB) address of a process in
    order to display information about the process.

2    /ID

       /ID=nn

    See the description of /INDEX, which is functionally equivalent
    to /ID.

3    /INDEX

       /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.

4    /NEXT

    Causes SDA to locate the next valid process in the process list
    and select that process. If there are no further valid processes
    in the process list, SDA returns an error.

5    /SYSTEM

    Specifies the new current process by the system process control
    block (PCB). The system PCB and process header (PHD) parallel the
    data structures that describe processes. They contain the system
    working set list, global section table, and other systemwide
    data.
