This manual is intended as a simple introduction to the writing of adventures using GAC. The Graphic Adventure Creator is best thought of as a small programming language specifically designed for the writing of adventure games. Although it is smaller than other programming languages such as Basic or Pascal; it can perform all of the complex tasks needed to write an adventure program; and although the instructions may seem a little complicated at first, a little time spent studying this manual will enable you to write your very own large scale adventures, far more easily and efficiently than in basic or machine code.
