Since this thread is of a subject matter not suitable for discussion on Omnimaga and presents a potential legal risk to the site, I'm locking it. @Aslr: If you would like help with the material or with learning to program, please post another thread. Thanks  EDIT: Unlocked since the discussion appears to have gone in a more productive direction. Also, this program comes highly recommended by Darl181: http://www.ticalc.org/archives/files/fileinfo/255/25555.html

Sorry, but we can't help you illegally obtain software. Also, if you have some issue that prevents you from learning the material otherwise, I'm sure the school would be willing to accommodate your situation.

It doesn't compute the actual square root, only an approximation to it. That means that the interpreter will always see a rational number, whether or not the true square root actually is rational.

It limits the number of times the loop will check, since one of the factors of any number n is at most sqrt(n).
That said, the routine given will take a loooong time for large primes.

Okay, I watched the video and all I can say is that it doesn't answer my question in the least: Why did Microsoft choose not to extend the well developed, debugged, supported, documented and accepted version of their OS developed specifically for low power systems and instead try to build an OS for all computers (which is pretty much doomed to fail)?

I find it strange that they're rebuilding an entire OS when they have the nice Windows CE line, which already supports ARM and many other platforms besides. Plus, developers are already used to writing for CE, since it's well documented. Furthermore, it's optimized specifically for less powerful devices like tablets.
Anyway, I won't be buying a tablet because I don't have a reason to. I want to be able to do more with my computer than check my e-mail.
EDIT: As for HTML/Javascript/CSS, good luck writing non-trivial programs in that, such as the HTML/CSS parser that Firefox uses (written in C). HTML and CSS technically aren't even programming languages, so if that source is correct, then the only real language available will be the mess that is Javascript.

I'm amazed that TI is so aggressive in their ways... Sony vehemently blocked downgrading of PSP firmware, but that was to prevent software piracy. Here, that isn't the case at all. Are they really losing any money here? I seriously doubt that anyone is not buying a calc out there because of lack of PTT. Especially when the very large majority of the public don't even seem know that they can upgrade their calcs. Even then, they won't be able to completely phase out the older models floating around.
Such a shame... will updates ever benefit anymore?
Sorry, off topic: "Twerty...?" Just going to say that Twerty is *not* me under another account to avoid any possible confusion

This topic has been moved to Axe Language because it fits more closely with the theme of that board than the current one. http://ourl.ca/11580

Giving you the answer (IE writing the program for you) doesn't really help you learn the language, so here's a pointer in the right direction: rand^5+1->X
[0102030405]->L1
"ABCDEF"->Str1
3*x-2->Y
.perform Substring operation on array pointed to by Str1.
.Be careful to handle the case where the starting location is greater than 3, as will often happen if X can vary between 1 and 5
For(X,1,20)
End
.no need for ipart in Axe, since Decimals aren't supported.
5->A
Be sure to keep in mind that you can't always just take BASIC code and easily translate it into Axe, particularly with the high level commands like Sub(). Axe might look like BASIC, but it requires a slightly different mindset. EDIT: I'm going to move this into the Axe discussion board, since it's more likely to get help and the topic fits in with that board better.

I'm probably in the minority here, but I've been using 2.53/2.55 for a couple years now with less than 3 RAM clears due to the OSes...
EDIT: @Jim, the boot code doesn't force PTT, which is also present on the normal calcs.

No, it switches the register set that's currently swapped in. The Processor has two register sets in Privileged mode: Regular and banked (which map to r8-r15). The GCC doesn't use the banked registers, so they're free to the ASM programmer to mess with. I doubt the OS uses them much either with the probable exception of error handling. Needless to say, I love abusing the banked registers

Well, the first routine is for ASM coders to access the banked registers that GCC doesn't touch, so it wouldn't really have much use for C coders (except to crash their code). The second routine is quite simple to fix. Just add "mov r4,r1" to the end of the code, with appropriate replacement of rts.
EDIT: changed.

About all the inevitable TI knocking: Keep in mind that the ASM commands still work. The 84 is not a mini-Nspire.
