Everyone pointed out the correct answer, that I was trying to make a floor much too large. I just scaled the room down down a quarter of the size I'd enlarged it to, and it compiles and runs fine. I'm not a computer engineer, I'm an artist with a passion for computers since they came out with the first ones. I learned to program in machine language then because you had to. Now, I should know how to write Gamestudio code but I hadn't used Gamestudio since A6 and WDL, and skipped A7. I've been spending time learning endless distracting graphic programs with their own complexities, 3ds Max, Blender, Lightwave and numerous paint programs, all of which have a learning curve. I've finally realized that for my money, 3D Gamestudio is the best program to realize the applications I want to create, bought A8 and need to get comfortable with lite-C. Thanks again, Superku and Redeemer.
