Does anyone know of any good resources for programming the 84+ CE?: Re: Does anyone know of any good resources for programming the 84+ CE?

The vast majority of programming techniques are directly transferrable from the original TI-83/84+ to the CE. After the CE was released, we updated our Command Index to include the few new commands that were added to the TI-84 Plus C Silver Edition and the TI-84 Plus CE.

Is there any specific information you are looking for?

All I can seem to find are resources for the TI-83+ and the original 84+, but nothing for the CE.

You cannot do this in TI-Basic.

If you want to though, you can create a custom list with up to 5 letters in the name, and store your number(s) in that.
So you could do:

5->⸤APPLE(1

The (1 is important because it specifies what index of the list to store your number at. Also, because it's the first index, the calculator will automatically create the list for you, if it doesn't already exist.

Hope this helps!

But do note that this takes up more space, and if you're only using the list for one value, your program will look cleaner if you just use a normal single letter variable instead.

example:
5->A Works
5->Word error

so i want to make variables with more than one char in the name but that gives me an error

dim( is your best friend here: if [A] is a 3x4 matrix, then dim([A] will return {3,4} as a two-element list. From there, you can do as you need.

Hello everyone, I'm Robert and I'm sort of new to programming Ti-basic. I have a Ti 84 CE. I'm looking for tips, resources and/or direct community feedback on if there is a way to get user input on my calculator that can be added to individual elements in a matrix on the fly from a program that I'm writing. The user would be asked questions, their answers would then be stored in a matrix. The size of the matrix would be determined by the user's input and further input would determine the individual elements. Further more the elements in the matrix would need to be extracted from the matrix and displayed. I'm not asking how to get user input or how to display that input. I'm only asking if there's a way to dimension the matrix from a program on the fly, how to store the info and extract the info from within said program.

Thank you for your time, support, advice and tips.

Just archive them.

Hit [2nd] and then [+], then 2 for Mem Management/Delete…, then 1 for All, then hit Enter to archive anything you want to keep in that list, and a * should show up next to its name. Hit Enter again to unarchive them.

One option may be to put your programs into a group, and ungroup them afterwards

I have a ti-84 plus CE, and would like to save my programs through memory wipes.
I have a teacher who makes us completely clear our ram before tests. I want to quickly state that I am not going to use this to cheat, I only want to save my programs through a wipe so I don't have to bother with reuploading them afterwards.
I'm not sure if this is possible or not, but it would be helpful.
Thanks

How do I fix this issue with the inString( command?: Re: How do I fix this issue with the inString( command?

It looks like you’re using a sequence variable on the calculator, whereas in your code you have lowercase letters in Str8. It’s important to note that the blue u, v, and w variables printed on your calculator are not the same as the lowercase letters in Str8. In order to type the proper lowercase alpha letters on your calculator, you’ll need to run this as a separate program:

Asm84CEPrgmFDCB24DEC9

(or if you don’t have a CE, I think the token will just be AsmPrgm at the start)

Once you run that program, you’ll be able to hit the alpha key twice and then type the green letters in lowercase. Again, the blue letters won’t work because they are variables.

I am writing a program that breaks apart strings base on certain criteria. For whatever reason, when I try to use the inString( command to find lowercase letters in a prompted, user-inputted string, it acts as if it has not found it and returns a 0. However, if the lowercase letter is written into the code of the program, it functions properly. I have included some pictures of the program's text and screen output. It's crucial that I have this issue fixed, so any help you can give please do, I'm all ears.

You can also use the "Str▶Equ(" command and then graph the resulting equation.

I am not sure if I am fully understanding your question, but I believe I may have the code to solve your problem.

Do you think you could print out the whole code of your program? I don't think I quite understand what you're asking.

Hello! I was wondering if its possible to graph a string,
Let's say that I have the equation 1/2X+3 stored into Str1, I can put this into the Y= screen, put when I hit graph, nothing happens, anyone know how to fix this?
Thanks!

Hi i have been making a logBASE rewrites and i’m trying to change exponential change into the log form but for some reason it doesn’t show the subscript on the home screen, and also it would be nice to know how to do the same with superscript.

Thanks for any help 😊

Here is my code if that helps

Lbl EL Disp “X Input X Disp “B Input B Disp “Y Input Y “logBASE(“+toString(Y)+”,”+toString(B)+”)”->Y1 Equ>String(Y1,Str1) Disp Str1+”=“+toString(x) Pause Goto T

Thank you! The List & Matrix One-Liners page you gave me looks very helpful, it seems I was not able to find this page when researching for an answer. I still don't completely understand what is going on in these lines of code, but when I have the time, I'll look into it and figure out how to incorporate it in my program. If I have any more questions, I'll return here. Thank you!
