I was working on a to-do list project I had planned, and working on creating a text engine for it. I may have simplified JWinslow's engine (the only one I know of, and can get my hands on) to a very small program. The program uses L1 to display the letter. To display your own text, simply input a number corresponding to a letter (A being 1, Z being 26, etc).

When you have text that's longer than the screen, it will wrap. There's one downside, and that is that you can't have any number in L1 be larger than 26.
Here's a working prototype. There is no program protection, so you have to make sure the numbers are within the parameters.

Interesting, although using a list instead of actual text might make it very tedious to type in long sentences, plus it might take a lot of memory when storing large strings as list.
