Here is a random example. I'm trying to figure out what this is called:
56/23/26/56/38/54/39/12/23/34/45/56/67/78/89/90
I saw that type of thing in a few scripts, where it was the only thing in the entire script.
If I can learn how to use it, I could encrypt a script. I've noticed that these types of things actually do something in-game.
I'll keep looking in the wiki.
It's just ASCII.
You can find a an ASCII table here
