check to see if a window is open

[Horrid]

I need to be able to check to see if a window of a certain name is open so that if a button is clicked it knows if it should load content into the window or a frame. What is the code to check to see if a window is present?

<b>var is_it_there<br>
IF window.parent.<i>(window name)</i><br>
THEN is_it_there = &quot;yes&quot;</b><br>
<br>
OR substitute<br>
