Okay, obviously you know what this one is about. To define the problem a little more, I tried using the randomize statement followed by a value of 800, but that makes it even worse.

Randomize 800
SpriteX# = rnd(800)

This always ends up at the same place - can anyone tell me how I can get a number that isn't the same every run?

Randomize seeds DB's random number creator. Each seed will produce a known set of values. So always seeding with a constant will produce the same result.

To vary the SEED, and make the randoms appear random, most people use the TIMER() function. Since it's a rapidly changing number and will be different each time you run the code.

Randomize TIMER()

Spritex#=rnd(800)
