Note that the part near the end of the introduction in the game about Free ZZT was written before Free ZZT was written, so it is not fully applicable now. However, XYZABCDE.ZZT remains public domain, and it works with FreeZZT as well as the official ZZT executable file.
If you want to cheat at it, you can, but of course is better to try to win without needing to cheat at it (I have win without cheating at it, so I know it can be).
If you have further questions/comments/complaints, then please ask a question/comment/complaint.
Perhaps I should also add the link:

I have set up a NNTP to discuss ZZT and other stuff.
