MS Word 2007 (and probably earlier versions) have the ability to do a basic document compare, useful if you're at a location that doesn't have more advanced comparison tools for TSQL. Just load your scripts into separate Word documents, click on the View ribbon, then click on View Side by Side. I know there are a lot of tools (free) that will do text file comparisons which accomplish the same or better, but that requires internet access, file download and perhaps getting by domain security, etc. Maybe one day it will help you when you're in a hurry.
