We're going to follow @Patrick Tingen (Axians)​'s recommendation and play "ADVENT OF CODE 2025". Please allow me to directly copy and paste from his post here.

~~~~~~~~

Do you like coding? And a little challenge? And a little fun?​

If three times a yes, then Advent of Code is something for you.

What is it

In their own words: "Advent of Code is an Advent calendar of small programming puzzles for a variety of skill levels that can be solved in any programming language you like". So that includes the ABL as well. And the good news is: it's free, although you are invited to become a sponsor for any amount you like.Every 2 days, starting 1 dec, you will get a small puzzle that you have to solve. You can use any method you like, pen & paper, excel, python, abl, gwbasic or whatever you like.

Why is it fun

I rarely have to deal with recursive procedure, breadth-first search, Dijkstra or similar techniques in my day-to-day work, so using the ABL in many unusual ways is fun to me. But even more, when I'm done, I like to see how others solved the problem and that's where you come in (HA! admit it, you didn't see that one coming, did you?)
