Adventure Language Programming System

Adventure Language Programming System is a program designed for creating text adventures on multiple systems.

The program came complete with a premade game called Mystery Mission. As the player sits in their hotel room, they hear a mysterious knock on the door. When they answer, a man falls dying into their room. Given a single clue, the player must solve the riddle of why numerous assassins are out to end the player's life.

All commands are via VERB NOUN entry, and there is a save/restore feature.
