process-spec

    Specifies a process currently under debugger control. Use any of
    the following forms:

    [%PROCESS_NAME] process-  The process name, if that name does not
    name                      contain spaces or lowercase characters.
                              The process name can include the
                              asterisk (*)  wildcard character.
    [%PROCESS_NAME]           The process name, if that name contains
    "process-name "           spaces or lowercase characters. You
                              can also use apostrophes (') instead of
                              quotation marks (").
    %PROCESS_PID process_id   The process identifier (PID, a
                              hexadecimal number).
    [%PROCESS_NUMBER]         The number assigned to a process when
    process-number            it comes under debugger control. A
    (or %PROC process-        new number is assigned sequentially,
    number)                   starting with 1, to each process. If
                              a process is terminated with the EXIT
                              or QUIT command, the number can be
                              assigned again during the debugging
                              session. Process numbers appear in a
                              SHOW PROCESS display. Processes are
                              ordered in a circular list so they can
                              be indexed with the built-in symbols
                              %PREVIOUS_PROCESS and %NEXT_PROCESS.
    process-set-name          A symbol defined with the
                              DEFINE/PROCESS_SET command to represent
                              a group of processes.
    %NEXT_PROCESS             The next process after the visible
                              process in the debugger's circular
                              process list.
    %PREVIOUS_PROCESS         The process previous to the visible
                              process in the debugger's circular
                              process list.
    %VISIBLE_PROCESS          The process whose stack, register set,
                              and images are the current context for
                              looking up symbols, register values,
                              routine calls, breakpoints, and so on.
