A while back, I purchased DarkBASIC online and noticed that it came with a Programming Manual. It was helpful (and had less errors than the directions located in the files for some reason,) but I also found out it teaches you how to make a First-Person Shooter. I typed in the code accordingly (and looked up errors on the forum) and it runs the EXE, but all I got was a blank screen.
For reference sake, here is the entire code I used from the tutorial

While no errors were found, I noticed something interesting in "TUT3C."
Quote: "As you can see, each subroutine has a name that describes what it does. At the moment they are all empty and contain no code. Later on in the tutorial we shall fill these subroutines with commands."
I didn't see the "later on" portion of this tutorial. I'll look into this, but I can't help but wander if there's more that's missing than this.
Any help is appreciated. Thank you!
Oh Lord! A beginner!
