  Use the monitor view to:

   -  Monitor the value of a variable or an expression during the
      execution of your program

   -  Watch a variable during the execution of your program

   -  Change the value of a variable

  To add an entry to the monitor list, select a variable name or
  expression in the source view and click on the Monitor push button.
  The debugger displays the current value in the monitor view and checks
  and updates the displayed value whenever it regains control from your
  program (for example, after a step or at a breakpoint).

  Monitored variables and expressions are listed in the Monitor
  Expression column.  Their values are listed in the Value/Deposit
  column.

  The button in the Watched column indicates whether the variable is
  being watched (button filled) or not (button empty).
