    This new function APAR provides RMF support for the gathering
    and reporting of performance measurements collected for
    usage of 2 GB memory frames.
    
    To expoit 2 GB memory frames, the Enhanced DAT Facility 2
    (EDAT-2) must be available.
    
    +--------------------------------------------------------------+
    >>> POSTPROCESSOR PAGING ACTIVITY REPORT <<<
    
    The Postprocessor Paging Activity report (PAGING) now shows
    values for fixed 2 GB frames and 2 GB memory objects of high
    virtual memory, as well as the size of the Large Frame Area for
    2 GB memory objects.
    
    New fields in the Memory Objects and High Virtual Storage
    Frames section:
    
    LARGE FRAME AREA - 1 MB FRAMES  Size of the 1 MB portion of the
                                    Large Frame Area.
                                    (This field replaces LFAREA
                                     SIZE in the section header.)
    LARGE FRAME AREA - 2 GB FRAMES  Size of the 2 GB portion of the
                                    Large Frame Area.
    MEMORY OBJECTS - FIXED 2G       Number of fixed memory objects
                                    that are allocated in the
                                    system and are backed in 2 GB
                                    frames.
    2 GB FRAMES   FIXED - TOTAL     Total number of 2 GB frames
                                    that can be used by fixed 2 GB
                                    memory objects. This value is
                                    equal to the size of the 2 GB
                                    portion of the Large Frame Area
                                    in units of 2 GB.
    2 GB FRAMES   FIXED - AVAILABLE
                                    Number of 2 GB frames in the
                                    Large Frame Area that are not
                                    in-use.
    2 GB FRAMES   FIXED - IN-USE    Number of 2 GB frames in the
                                    Large Frame Area that are
                                    in-use.
    
    Information about 2 GB frames and memory objects that are
    backed by 2 GB frames is only available if Enhanced DAT
    Facility 2 is installed.
    
    +--------------------------------------------------------------+
    >>> POSTPROCESSOR VIRTUAL STORAGE ACTIVITY REPORT <<<
    
    The Postprocessor Virtual Storage Activity report (VSTOR) now
    shows usage values for fixed 2 GB frames and 2 GB memory
    objects of high virtual memory owned by the address space.
    
    New fields in the High Virtual Memory Usage section:
    
    MEMORY OBJECTS - FIXED 2 GB     The MIN, MAX, and AVG values
                                    for the number of fixed memory
                                    objects that are backed in 2 GB
                                    frames, allocated with the
                                    indicated job.
    2 GB FRAMES - FIXED             The MIN, MAX, and AVG values
                                    for the number of 2 GB frames
                                    that are used by FIXED memory
                                    objects with the indicated job
                                    as the owner.
    
    Information about 2 GB frames and memory objects that are
    backed by 2 GB frames is only available if Enhanced DAT
    Facility 2 is installed.
