For anyone wondering i am reading the dark basic pro 2nd edition book. I've gone through chap 10 through 14. I've tested the game through out my creation with success. But when i put the final touches on it in chap 14 it now wont load correctly. There was alot of changes done but ive read my code over and the authors code over and cant find an error. Does CAPS matter, correct spacing??? I just cant find it. Both codes are below PLEASE HELP. The result i get is the score just starts going up, the level # goes round and round, the ball wont come off the paddle and all of the blocks wont show up. It almost seems like its resetting.
