That part of WarGames (the novelization) where Jennifer is the one who figures out the password to hack into the WOPR system (after David belittles her computer knowledge).

I always thought JOSHUA5 as a password (as in the novelization) was better than just using Joshua, as was done in the movie. The process of gathering clues, making guesses, and trying variations is better when it includes JOSHUA5. It shows the benefit of collaboration - having different perspectives that work together and come at a problem in different ways.

David shrugged. "It's sure worth a try."

I wonder when the JOSHUA5/JOSHUA change was made.

Below is the page of the novelization in which Jennifer cracks the code, and a Youtube link with the scene in the movie.
