1.2    /BUFFER_OBJECTS

    Displays information about system resources used by buffer

1.3    /CACHE

    Displays information about either the Virtual I/O Cache facility

    information on how memory is being used by the Extended File
    Cache facility can be obtained using the XFC extension described
    in Chapter 9.

    information is displayed about the size of the region, the amount
    of free memory, the amount of memory in use, and the amount of
    memory released to OpenVMS from the region. The granularity hint
    regions information is also displayed as part of SHOW MEMORY and
