open window object, then change pages. still same window?

[Gilbert]

Hi all,   I'm trying to wrap my head around the idea of the window object and the document object relationship.   I've read some really good explanations in stackoverflow and others.  I have a pretty good grasp of it so I tried an experiment.   If the window object opens in the browser, and then the document object opens in the window, then if I change the document, will the window object remain the same.  I tried make 2 simple html's - in the first I set a variable like  window.myVar = "myValue";.   I was able to change the value with a button so it was working fine, and then I used an <a> href to change to a different document.   I tried to reference the window.myVar but it came back 'undefined'.   If you change documents in a window, does the document always come with a new window, or am I doing something wrong here?   Like I said, I've read a lot about the window and document object, but I couldn't see that this was addressed.   Thank You for any response....
