You can only pass 1024 characters in the query string. If your text file is going to contain more than that, you'll encounter problems. Also, what's "parent.comment.location"? I've never seen anything quite like that before.
The best way to pass text like this will be either to pass the filename to the next script and let that script open the file or to stick it in a hidden field and POST it to the next page.

Seems like you've got it just about right. All you have to do is have the page loaded in the frame take a database ID as a parameter. The page then loads in your frame and queries the database (or the filesystem) to load the necessary text. It seems that you're trying to pass the text itself, when it's better to pass a reference to the text and to have the newly loaded page load the text.

That's pretty basic stuff. If you're not familiar with such basics, you need to find a book or tutorial on PHP fundamentals. Essentially, I'm suggesting that you pass either a database or a filename in the query string (http://www.url.com?id=00001, for example) and then use that id in the resulting file to query the database or open the given text file. This is something you'll do over and over again in PHP development, so understanding it now is crucial. There are probably tutorials on this site that will provide general information that'll help you out. I'm afraid I don't have time to rewrite what many others have already written.
