Check out SetSpriteUVOffset

You can make a sprite that is wider than your screen and scroll the texture by setting the UV offset. Make sure the ends are seamless so that you don't see a join.

...or use a tilemap. Just remember to copy the first screens worth of tiles to the last screen of tiles so that it can loop around.

Then of course you have procedurally generated backgrounds that could go on and on forever For example, if your background is a space scene, you could have a bunch of planet, star, nebula etc. sprites and simply use the RANDOM function to place them. Make sure you set a random seed at the beginning of your code so you get the same sequence of 'random' positions on each run.

Quite often I create randomly generated backgrounds (using an integer seed if you want the background to always be the same). If it is a constantly moving sidescroller (for example) this is a great way to deal with an 'endless' background as you can just "randomly" add scenery as you go along and delete scenery as it goes off screen. Attached is a current WIP as an example of what can be done easily although I've only added trees and bushes as yet... If you play the game a couple of times you'll see that the background and enemy are always the same but actually you can play the game for hours (if you don't die and it's currently pretty easy not to die) and still have the same enemies and background each time.

Never underestimate the usefulness of "Random"...

Imagine if Hanna Barbera had Random capabilities in their cartoons. Scooby Doo and Top Cat chase scenes would never be the same again!

Remember to set the image to X and Y wrapping - otherwise the UV offset may not work. I think the command is SetImageWrapU(img,1) and SetImageWrapV(img,1)

I am the one who knocks...

Here's an example of how you could easily add to your code to make the background endless:
