    <BR>The Stack Window allows users to view the call stack and jump between

    levels of the stack.

22
    The Stack Display consists of a listbox which displays levels of the call stack
23
    on per line. Each line contains the level number (useful when using the
24
    <A HREF="console.html">Console Window</A>) and a description of the function executing
25
    in that level. Typically, the function name and either the address of the function
26
    or the file and line number where the function is defined are displayed. The
27
    Stack Window may also be used to jump between levels of the stack.

31
    Navigation of the Stack Window is accomplished by clicking on the desired level
32
    with the left mouse button. The <A HREF="source.html#display">Source Window
33
      Display</A> updates to show the selected frame. All other secondary windows,
34
    <A HREF="register.html">Registers</A>, <A HREF="watch.html">Watch</A>, and
35
    <A HREF="locals.html">Locals</A> update their displays for the selected frame.
36
    <BR>

38
    <H2><A NAME="display_lvl">Changing Stack Levels</A></H2>
39
    To switch frames, simply click the left mouse button on the desired frame and the
40
    debugger will switch contexts, updating all windows. The selected frame is highlighted
41
    (in gold, by default).
42
 
43
    <P>As an alternative, changing stack levels may be accomplished via the
44
      <A HREF="source.html#toolbar_frame">Frame Control Buttons</A> on the Source Window's
45
      Toolbar. These buttons may be used to change frames one level at a time (either
46
      immediately up or immediately down) or to jump to the bottom-most stack frame.
47
      See <A HREF="source.html#toolbar_frame">Source Frame Control Buttons</A> for more
48
      information.</P>
