Yeah so does BatLib. And Xeda, the :" trick works on at least the 2.55 MP and there's not a newer OS. I use it for my pure BASIC programs. It's there so Ans will look all pretty :)
Yeah, if you have BatLib, you can use dim(22,"H3XC0D3H3R3") don't use the C9. And don't try running that code I just gave you either, since it's not code it's leetspeak so you get the idea. I don't want to be responsible for bricking someone's calc with that. I doubt it would even run since there's an "X" in there but you never know. And as Boba Foxx said, Omnicalc has one too. I think most ASM libraries have one now that I think about it.
