Here, what you wanted wasn't too much, so I put together a little mini-tutorial for you on it. You should still read some of the other tutorials, though, so you can learn about variables and all that good stuff.
Just be warned that this is the easy part. Stuff like moving your character around will be much more challenging.
`These are some settings for SYNC, which is our way of updating the screen.
sync on : sync rate 60
`By the way, this is a REM statement. It will be completely ignored
`when the program is compiled.
`This causes all sprites, including the background, to be draw first.
`This means that the 3D world will be drawn on top of them.
draw sprites first
`Put your image name in here. This command will load it and
`store it as image number 1
load image "background.ext",1,1
`This command will make a sprite, numbered 1, that uses image 1.
`The sprite is at 0,0, which is the top-left corner of the screen.
`As you go further to the right and down, the coordinants increase.
sprite 1,0,0,1
`But your world's filename here. It will need to be an object
`with the extension .X, .3DS, or .DBO
`This command loads that object as object number 1
load object "world.ext",1
`Your object may be too big to fit on the screen, so you can use
`this command to fix that. Or, it may be too small, so do the same.
`The scales are percentages
scale object 1,100,100,100
`This positions the camera a little ways out on the z-axis...
position camera 0,0,80
`...and points it back toward the origin (0,0,0), which is where
`your object is.
point camera 0,0,0
`This is the main loop. The program goes through the commands
`above only once, but the stuff in this loop will continue to
`be executed until you send it elsewhere with a command like
`GOSUB.
DO
`This will move the camera left if you press the left arrow.
`Pretty easy.
if leftkey()=1
move camera left 1
endif
`Guess what this does?
if rightkey()=1
move camera right 1
endif
`Update the screen
SYNC
`End of the loop, this is where the program goes back to the DO

Los Mineros are on leave...
