With the DRUGWARS example... how is it working? Did it learn about the game by reading transcripts of its gameplay? Curiously, it cannot tell you how much money you have in your wallet, and I can't modify the prompt to make that work. It always responds with some version of: C:\DRUGWARS.EXE I'm sorry, but I do not have information on your current amount of money. In the game DRUGWARS.EXE, you are responsible for keeping track of your own finances. You can use the SELL and BUY commands to earn and spend money, but I do not have the ability to provide you with your current balance. C:>
