Disabling comments on pages

I’ve browsed through the forum and found several threads related to my issue, but I still can’t quite get my problem resolved. I apologize for cluttering the forum.

Basically, all I want is to disable the comment feature on pages (but keep comments on posts). I saw on another thread that there’s a line that needs to be deleted from the page.php. The probably is, I have no idea what that is or where to find it. Can someone help me? Is the process terribly complicated?

Thanks so much to anyone who can offer suggestions!
