If you select the name of a pointer (access) variable and click on the
  Monitor push button, the debugger displays the address of the
  referenced object in the Value/Deposit column of the monitor view.

  To monitor the value of the referenced object (to dereference the
  pointer variable), double click on the pointer name in the Monitor
  Expression column.  This adds an entry for the referenced object in the
  monitor view, which is indented under the pointer entry.  If a
  referenced object is an aggregate, you can double click on its name to
  display its elements, and so on.

  If you are debugging programs written in C or C++, you may want to add
  a new push button to the push button view, one that monitors a
  dereferenced value.  If so, you enter the following command in the
  Command field of the Customize dialog box:

         monitor *%s

  Command help topic.
