How do I read contents of another window?

[ikb]

how can I read the contents of another window or frame from a javascript?

for example: I have 2 frames:
the top frame shows a random text.
in the second frame I want a script that reads the text and, shows it.
Thanks for any help...

With Content I think u mean a form?

Frame:
document.framename.boxname.value
(not shure)

Other window
If u want to work with popups, here are 2 links:

:(, It didn't help. Maybe it'll help if I clearify myself:
In the frist frame I have a site from a third party, actually not even a site, just a text file with information.
I want to somehow read it by the other frame.
