ok, I need to make a simple tile based game. I kind of know how to create the world, but I need help in getting my art on to the screen from an array. Do I need some ASM function to get bitmaps on???

No, you don't. Ever heard of DirectX? Or even Allegro if you're working in DOS? These are called "graphics library". These "graphics library" helps the "programmer" to "game program".
