The instruction view displays the decoded instruction stream of your
  program---the code that is actually executing.  This is useful if the
  program you are debugging has been optimized by the compiler so that
  the information in the source view does not exactly reflect the code
  that is executing.

  To display the instruction view, choose Views...  from the Options menu
  on the main or optional view window.  When the View Selection dialog
  box appears, toggle Instruction View.

  By default, the instruction view automatically displays the decoded
  instruction stream of the routine in which execution is currently
  paused.  The current-location pointer, to the left of the instructions,
  marks the instruction that will execute next.

  By default, the debugger displays line numbers and memory addresses to
  the left of the instructions You can choose not to display numbers or
  addresses so that more space is devoted to showing instructions.  To
  hide or display line numbers, toggle the Display Line Numbers button
  from the File menu on the instruction view.  To hide or display memory
  addresses, choose Show Instruction Addresses from the File menu on the
  instruction view.

  To copy memory addresses or instructions into a command you are
  entering at the command entry prompt, select text and choose Copy from
  the Edit menu in the instruction window.  Then, position your mouse
  pointer at the command you have entered and choose Paste from the Edit
  menu on the main window.  (You can also select instruction text to be
  used with a push button command you click in the push button view of
  the main window.)

  To set breakpoints from the instruction view, toggle the breakpoint
  button next to the instruction of interest.  The breakpoint is set in
  the source display, instruction display (if the instruction view is
  open), and breakpoint view (if the breakpoint view is open).
  Information on the breakpoint is continuously updated in the source
  view, and in the instruction view and breakpoint view if they are open.

  You can also set breakpoints and change breakpoint status by pulling
  down the Break menu from the main or optional view window.

  After navigating through the instruction view, to redisplay the
  location at which execution is paused, click on the Call Stack menu.

  To display the instruction stream of any routine on the call stack,
  choose its name from the Call Stack menu on the main window.
