My calculator cannot crash, it's too good. Either that, or my programming rocks, because I don't let anyone else program my calculator

BASIC programming? :)

You do know that only Assembly can crash your calculator, right? ^_^

Uhhh..... BASIC *CAN* crash the calculator... You have to be pretty creative to do it though... (And I don't just mean an ERR: message.)

I have had it (my TI-92+) crash when I was just doing math problems on the home screen. I even once had it erase all my apps & archived variables from such a crash.

How, exactly? I've had this happen to a number other people's calcs that I loaded one of my BASIC programs on. Out of about 25 people, about 10 experienced a crash. I was under the impression that a crash because of a BASIC program was impossible...(so naturally I blamed the occurences on other programmers...)

There are plenty of glichtes in the TIOS that you can take advantage of. However, it's been so long that I can't remember details for any of them.

There's all kinds of strange stuff you can do by converting strings and equations back and forth using the "Eq>Str" and "Str>Eq" commands.

Yes, I've actually had it happen on my 85, but it is very unlikely...

The only reason that it would crash your calc is if you were TRYING to have it crash your calc... ^_^

I can't even think of a way to crash it when you're even trying.. anybody know?

Actually, you can use Omnicalc, with the ram recovery feature. The function real(32,0).

it's funny how Omnicalc makes your calculator crash, yet saves the settings before a crash.

Yes, but that's not *truly* BASIC.. it uses the App.. I was wondering if there were any way possible to crash the calc using pure BASIC commands

Someone (I want to say it was no_one_2000_) posted a few lines of basic that would crash one of either the 82 or 83+, maybe both, in a really really old old ancient long ago survey. Unfortunately, I can't remember which survey, when exactly, who it was, or what the code was. I just know it was there, and it apparently worked. So there's your proof. It can be done.

Yes, it is possible to erase your ram using *true* basic. I don't remember any combinations, but certain combinations of characters can reset your ram in the correct order. I've done it a couple of times before.

Create a string containing some strange char like the one you get when you press the EE key, then convert it to an equation and back a few times.

Um, My 84-plus crashes all the time. Most often at the home screen. Sometims in BASIC programs. It never gives me an error message. no divide by zero error, for example, it just crashes, clearing the ram. (Fortunately, I have Omnicalc (Thanks to Michael Vincent of course))

I think it's broken.

By the way, I wouldn't really mind my calculator crashing, since I can restore it and all, but Omnicalc can't keep the clock going. Oh well.

That happened to me a while back (using my TI-83 SE). I noticed that when I had Omnicalc UNinstalled, it didn't crash...

But that was a while ago, and it hasn't happened with the current version of Omnicalc. Is your Omnicalc an old version, by chance?

You wouldn't happen to be using Omnicalc commands with your BASIC programs, would you. I came up with some creative ways to crash 83+s using those.

ExecAsm("CD454D"

Guarenteed RAM clear!

There are so many others...

do you use MirageOS by any chance?

Mirage OS is supposed to be able to run BASIC programs, right? (rhetorical question.) Whenever I try using BASIC programs on Mirage, it crashes and clears me ram.

(Example Program)

:PRGMTEST
::"Program Test
:Clrhome
:Stop

Mirage executes the program and then crashes. IF anyone can tell me what I'm doing wrong to crash Mirage, please tell me.

that is because mirageOS is not to stable with basic programs i think it might be something with the stack but I'm probly wrong.. other people might know. i had mirageOS installed and my calculator started giving random ram clears and eventually my whole calc died (for good (i've tried everything)).

The joy of nested parentheses.. :-D.. and oh yea.. Mirage seems to run my BASIC programs just fine.. in fact, it has never (from what I can remember) crashed my calc.. it did with version 1.1, but 1.2 hasn't yet..

By Gar! Your right!

What version MirageOS do you have? If it's anything below 1.2 (the latest), get rid of it immediately! (From personal experience, 1.0 and 1.1 cause crashes running any BASIC programs...)

Create some kind of infinite loop and run it until batteries are wasted. When the calc goes out the ram will get erased :D

Only because the RAM checksum doesn't match the RAM contents; it's the same thing as taking a battery out during a computation (such as graphing). If you have RAM Restore, it should still hold.

Well, it might depend on what type of batteries you're using. I've found with my rechargable batteries, when they get low, the calc just shuts itself off with no harm done (and turns back on only with the low battery message). Admittedly, I have not tried this while running a program, but it works when I try to archive something.

That's different from crashing though. It can also be stopped (speaking from an 89 user prospective) simply by pressing the ON key. the BASIC crashes people want are more... pieces of code which take advantage of flaws in the OS to cause more immediate undesired results. But I feel where you're coming from. I used to proud of my C++ programs that quickly ate a computer's RAM. mmm... recursion...
