63- Instead of starting a new line, you just write \n
64- Every time you say "if" you always end the sentence with "EndIf"
65- Same as 64, except it applies to while, for, and try
66- It drives you crazy when people refer to the TI-83, TI-83 SE,TI-84, and TI-84 SE collectively as "the 84"

12. When you calculator batteries die, you get new ones from the nearest battery-powered object. 13. When you have to write "inspire" in an essay, you write "nspire" 14. Same problem as 13, you write "ndless", not "endless" Also, DJ, don't forget to indent you paragraph in Number 6, it should be Output(3,1,""  .

Have you installed the 64-bit patch for TI-Connect? That might be the issue.
I could be wrong, but I don't think this is the issue because TI-Connect has almost nothing to do with the TI-Nspire. Also, I don't think the patch is available from TI anymore; the last time I checked they uploaded a new completly compatible version of the software. Do you have Computer Link 1.4 installed on your computer with version 1.3. If you do, try uninstalling it, as Ndless might only detect the one version.

Paint.NET is fair for Pixel Art. I does let you get a good zoom on the sprite, but I still prefer to use MS Paint.

I don't think the 68k calcs are completly dead. I see TI-89s in many stores where I live, but I have never once seen a TI-Nspire CAS in a store. Also, my school purchased new TI-89s for to be used in precalc and Calculus classes (they used to have 83s). Also, although a TI-89 or TI-83/84 emulator would increase the demand for a Nspire among programmers, I do not think that this would cause a major downfall of the 68k series. At my school, I am the only person who even has an idea on how to program (I amaze people with a qradratic formula program  ), and I can never see these people figuring out how to send/use an emulator on the Nspire).

Hi. I have been trying for several days to get the TI-Nspire emulator installed on my computer, but I can't extract the boot 2 image from the .tno file. I change the file extension to *.zip and Windows gives an error message saying that the files cannot be extracted. In the setup video, it looks like some third party extraction software is being used, not just the built in Windows extractor. Does anyone know how I can extract the file to get the emulator working? Thank you for your help!

I have another problem with lists in C. How to I add strings to a list? For example, I want the list testlist[4]={"Test","List","Hello","World"};How would I create this list. I tried declaring it as a character: char testlist[4]={"Test","List","Hello","World"};but this did not work. What am I doing wrong? Thanks again for your help!

Hi. I am having trouble writing a program in C for the TI-89. I am very new to the language and I still have a lot to learn.
In TI-Basic, I have programs that can take a list, ex: {1,4,3,1,7,9}, and will retrive a certain element from the list. For example, if I called for element number 2, the function would return 4.
Is there any way I can get the same feature in C. Would I use "lists" like in TI-Basic, or is there a different method. Also, I would have the lists pre-entered in the program. The program would not have to add data to the lists.

Bwang, I finally had the time to downgrade my OS last night and try your Raycaster. You did an excellent job. I wish I was as good at programming as you.

Another interesting thing is that it never "completes" the calculation. It is not really an error message, but simply a dialog box that appears. For example, if I type x+1 without having x defined, it actually "completes" the calculation, with the "answer" being "Error: Variable not defined" When using the CAS unsupported features, the dialog box appears and it goes right back to the original line, as if nothing ever happened. There could be just a line or two of code blocking the calculation from progressing.

Also, all of the CAS features are on the non-CAS, just not listed. Even those, such as taylor(, that are no where to be found in the catalog, get the error message "CAS needed." There must be some way to "unlock" the CAS features.

That should make the program better. Thanks for your help! I have to finish this program fast before my Chemistry final. I still have a long list of programs to go.

Hi. I have a program that uses Goto [whatever] in an If...EndIf block. The code is below. It is a [incomplete] Gas Laws program for the TI-Nspire. Because this is a program and will end, and not keep playing like a game, will I use RAM memory. Also, if this does use memory, could I fix it by making it go back to the original If...EndIf block with a lbl at the end of it and have it display the answer from there? Thanks!

Every time a new video is posted, I want to try this more and more, but I have OS 2.0 and I need the programming tools in 2.0 for Chemistry programs I use in school. I wish this would work on 2.0.  I hope Ndless 2 comes out soon.
