Okay, I recently bought The Black Art of 3d Game Programming, and found that the source is in Borland C++ version 4.5, so I got the compiler. However, when I compile and build the applications, when I doube click the .exe that I built, it comes up with an illegal operation error. I also notice that the application is in a regular window, unlike the book's application which is in DOS. Can anyone help me on what to do with this book, and how to make it's applications run properly?!

I've never looked at the book...but first guess...are you compiling for DOS or for Windows...under the Project settings? Check this first...
