The Heap Analyzer provides a graphical representation of memory
    use in real time. This allows you to quickly identify inefficient
    memory usage in your application such as allocations that are
    made too often, memory blocks that are too large, fragmentation,
    or memory leaks.

    For details on running the Heap Analyzer from within the
    debugger, see the VSI OpenVMS Debugger Manual.

    On OpenVMS Integrity servers, the standalone Heap Analyzer is
    started within the kept debugger using the START HEAP_ANALYZER
    command (see example).

    On OpenVMS Alpha, the standalone Heap Analyzer is started within
    the kept debugger using the RUN/HEAP command.
