Starting with a live debug of notepad which is our favorite example program the classic it is and, probably at the end of the list and so we're attached to notepad we'll do a .cls first, which is clear screen and, a lot of things we do in support is about analyzing things and then giving that information to some one else, alright, so there are a lot of tools that we need to do that say what we are up to and what the hell we're working on and understanding what's happening in the analysis process so far, and you'd probably agree that if someone doesn't write good case notes its like starting again, right? yeah, exactly, so you have to make sure that you document everything you do in our line of work yeah, and a lot of things about the debugger because it's text it's great, you have these antiquated text systems
