What do people use Venkman for?

I can't figure Venkman out.  Here is a 4 line script I am trying to Step
Into:

1) <html>
2) <head>
3) <title>test</title>
4) <script type="text/javascript" language="javascript">

5)  var a=1;
6)  var b=5;
7)  var c=10;
8)  document.write("<div>" + (a+b) + "</div>");

9) </script>
</head>
<body>
</body>
</html>

When I click on Stop in Venkman and then reload a page with the above script
on it and nothing else, Venkman halts the execution at line 5.  Then, when I
successively click on Step Into, these are the lines the debugger moves to:

5 (start) a, b, and c are undefined.
6 : a is 'void' and b, c are undefined.
7: a,b are 'void', c is undefined.
5: what the??  a,b,c are 'void'
6: a=1 and b,c are void
7: a=1, b=5, c is void
8: a=1, b=5, c=10

Is that what happens to you when you step through that simple script?  Is
Venkman broken?  How can anyone use this debugger if it exhibits that kind
of behavior?
