I have a holding page where the user must work with a child window that is open also. If the user closes the parent 'holding' window then the process does not work as smoothly. Not being a javascript person, what statement do I need to use in the 'body onunload=' that will reopen the browser window to the same page if the user closes it?

there will be no smooth solution for your problem as onunload fires not only when you press the X button but also when you refresh the page or navigate to other pages.

i suggest you use our previous method but using this code,

<!doctype html public "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<script>
var Cleaned = false;

function cleanUp(){
var URL = 'finishpage.html';
if(window.opener == null || window.opener.closed){
       window.open(URL)
      }
      else{
       window.opener.location.href = URL;
      }
      window.close();
}
</script>
</head>
<body onunload="if(!Cleaned)cleanUp();">
<a href="finishpage.html" onclick="Cleaned=true;cleanUp();">finish</a>
</body>
</html>

here in one Line

<body onLoad="Z=window.open('a1a.html', 'A', 'width=100 height=100')" onunload="(Z.closed)?'':M=window.open('index.htm');">

So it will LOAD a pop up a1a.html when the Page loads, variable Assign to it is Z, so you can open Child Window anywhere you want but assign it to a variable named Z. Then in unload event define the same path as the MAIN parent window.

so if the child is open parent will keep opening.

wouldn't body onunload="return false;" not do the trick?

It is better to close the popup window when "parent" unloads...
like this

var popup;
<script>
function closepopup()
{
if(popup)
if(!popup.closed)
popup.close();
}
</script>

<body onunload="closepopup()">
