We provide a set of functionalities (Modula-2 procedures) to interact with the game. Some procedures will allow you to get information and others to do something in the game. For example to move a player one step to the left. To that end we have written a library called PACSengine. The engine is taking care of the game, your program will interact with the engine to actually play a game.
So let us put it clearly for the last time: your
job is NOT to write the game!
