You have to install a jailbreak called ArTIfiCE. You could just look up "artifice 84 plus ce" to find it.

Here's the actual link, for posterity: https://yvantt.github.io/arTIfiCE/

There isn't a program to access it, but there is another way to get lowercase letters. If you go into your menu, go to language and change it to any language other than English. Then go into catalog (2nd→0). It'll be in the new language but don't panic. You want to access the first option (characters). Once in the GUI for the characters, press alpha twice and you'll see the lowercase option. Now do 2nd→on) Then turn your calculator back on, and you have lowercase letters!

Just use upper case for vars. It works fine.

What about this? It is in eZ80, but you could just copy and paste the code into SourceCoder3, check it, and then export it. It should give you a .8xp file.

Code:


I just tested it, and it works.

I just found out that you don't need ASM or any other program to have lowercase letters on your TI84+CE.

1. Press mode and change the language to a language OTHER than English.
2. Press “up” to affect the change.
3. Go to “catalog” (2nd + 0)
4. Choose the first option. If you selected Spanish (Español) as your language, it should be “Caracteres”
5. You should see a screen that allows you to type lower case. Test it out.
6. Quit that application (2nd + mode)
7. Press mode, again, and change the language back to English.

Enjoy you lowercase typing

It works, but this is more efficient, because you don't have to press [2nd][0] every time you type a letter.

I made a TI-Basic program compatible with any OS. To use it, just type what you want and press enter; the text will be saved to Str0. Otherwise, I recommend installing CEaShell. You can enable lowercase in the settings menu.

You don't. All you have to do, if you want just one lowercase is press “Alpha” twice.
If you want to type long text, do an “Alpha Lock” and press “Alpha” when you want to change between upper- and lowercase.

If I remember correctly The trick is rather to turn off the calc once you're in that Characters screen. Then the lowercase toggling feature will be enabled os-wide.

Does it work on OS 5.4.0.0034?

On every version as far as I know.
