I was poking around a tape containing some of my
old university stuff and found this.
It's a VAX/VMS Version 3.? DCL implementation of the
old game 'Animal'. It should work for later versions
of VMS. It supports saving and reading the question
database. It is probably one of the most twisted
implementations of this game. I was quite proud of
it when I wrote it. Use at your own risk!
