If you invoked the heap analyzer from within a debugging session, start
  your application by performing the following steps:

  1.  Click on the Start button in the Push Button Control Panel.

      The Message Window displays an "application starting" message, and
      the Start button label changes to Step.  The OpenVMS Debbugger main
      window pops forward.

  2.  Click on the Go button in the OpenVMS Debugger's control panel, and
      iconize the OpenVMS Debugger window.

      Memory events associated with your application begin showing in the
      Memory Map.

  (If you invoked the heap analyzer outside a debugging session, start
  your application by performing only step 1 above.)

  After your application is running, the Memory Map (and other parts of
  the heap analyzer display) are continuously updated to reflect the
  state of your application.

  Unless you intervene (by clicking one of the push buttons in the heap
  analyzer control panel), this updating continues until an occurrence
  causes memory events to stop.  For example, your application might
  prompt for input, the debugger might prompt for input, or your
  application might finish execution.
