The one CYOA book I remember the most is "Inside UFO 54-40" (#12 of the original series). Throughout the whole book you are searching for this utopian paradise, and there is actually a "Congratulations, You found it!" page in the book, but THERE IS NO WAY TO REACH IT! I didn't make a graph, but I remember searching through the entire book to see if there was a "turn to Page 101". There was not. So do we call that unreachable code? Should the book not compile?
I remember that one! I did the same thing -- saw the "you found it!" page, and then flipped through the whole book looking for a reference, and found that there wasn't one!
That "unreachable" page sounds like a private method with no references to it; nothing that wouldn't compile, but probably a good candidate for a compile-time warning message!
To stretch this somewhat silly analogy even further, we could call the process of flipping through a choose-your-own-adventure book in that manner a primitive version of using a decompilation tool.
Best of luck in your new pursuit, and good for you for not being afraid to step out of your comfort zone and go for it! I'm looking forward to reading more about it in the future.
