    Data Item
    This number stands for the Process Identification Number (PIN). Each process is uniquely identified by its own PIN. The easiest way to locate processes is by knowing this number. A single job or session can have many processes associated with it.
    This is the job or session number associated with the particular process. If the process is a system type (not originating from a user job or session), <sys> will appear in this column.
    Session/User Name
    This is the logon sequence as initiated by the user or job minus the logon group. Once again, if the process was spawned by MPE/iX and not with a session or job then <System Process> will be shown here.
    This is the program executed by the user. Some system type program names will be uniquely identified, such as “Spooler.”
    This is the code that represents how the file is being accessed by the process. R means read. W means write. L means lock.
    File Size
    This is the size of the file.
    Rec Ptr
    This is the current record number being accessed.
    This is the number that will indicate how far a process has progressed through that file.
