So today in the mail arrived The Elements of Computing Systems. I read through the first chapter, only to find out that it appears to be that the book wont have me design the computer, just look at the parts and improve upon them... But that's irrelevant. I opened up the hardware simulator, opened a chip, then tried to open a script. No scripts anywhere. I looked through the entire software suite, no where to be seen. Then, with Windows Explorer i manually looked. No .tst files ANYWHERE. Please please please help, this is incredibly irritating.

Also, when i do click on View>Script it just shows the same thing that is found in a .txt file under Bin\Scripts.
Edit 2: I also cant figure out how to edit the code in the HDL box.
All help appreciated.
