The problem with the AI isn't in the checking if the move is legal, otherwise it would actually make the move, not try to (if the Legal Move funtion gave back the wrong value, then it wouldn't continue looping). As for the illegal moves it tries, I think they are always in a place that already has a piece in it. The problem occurs in the AI deciding where to go and in what it treats as a leagal move, not with the leagal move checker. The Out of Memory error appears even if I stop the execution before I begin playing, while it shows the menus (which use the mouse):
The following is the code for the main module and the first sub it calls (other than the ones to show the mouse):
If I stop the execution (Ctrl+Scroll) after just clicking New Game, it gives me the out of memory error when I try to edit something. As for the stack, I'm not 100% sure exactly where in the AIMove sub it occurs, and it dosen't occur every time; I just disabled the loop in the AIMove sub (whenever it didn't go, I went for it), and the Out of Stack error didn't occur once. It might have only occured before I added mouse capabilities into the game (when it used on key gosub for the arrow keys; I didn't know what the "real arrow keys" gave to inkey$, so I used on key to trap the num pad arrow keys). If it occurs again (I'll play a few more games), I'll post where it happens in the sub. Thanks again.
