VEE Easter Egg - Xyzzy Command Generates Error Linked to Old Adventure Game

Using VEE, place a formula box on the screen and use the term "xyzzy" in your formula. Click outside of the Formula box and the message "I see no cave here!" is displayed on the VEE status bar. Run the program and an error box appears stating "I STILL see no cave here!"

In one of the first computer games, Scott Adam's Adventure, "xyzzy" was a magic word that allowed for teleportation. "I see no cave here" was one of the phrases used in the Adventure game.
