I got this buggy "Program": The program cannot evaluate that bolded line, however, I can calculate this : desolve_h(exp2vector(fx,y,x),x)//Nspire OS 1.6

I don't know If any of you had a similar situation to this one, but I really need help as this could be a way to get a Nspire CAS Cx. I bought two calculators at http://underwooddistributing.com/And then they when they site calculated the shipment it said it would be $3 (usd) for bringing it here [Brazil]. Then, I got this e-mail today: My question is: If their site made this calculation wrong isn't their problem and they should give me the product, or they may not sell this to me? Because I feel cheated by this whole system.  Sometime ago, I bought a book from a danish site, and it made the shipment calculation wrong too, but they assumed it was their error, corrected their site, and send me the product.  So I was wondering how does this work on the USA... Can anyone help me?

You mean the error you got? That's because you're defining a function that calls itself. You can't do that.
No I mean when I tried: Define f3(x)=f2(x)/(x-root) It doesn't appear as error, but it don't work I will post the code, so you can understand it better: Main function: Define vieta(number,grade)=
Prgm
:Local a,root
: Disp "The root are:"
: For a,0,grau,1
: If grade=1 Then
: root=newton2(number,15)
: Disp root
: Else
: If grade=2 Then
: newton3(number+a,15,root)→root
: Disp root
: Else
: If grau=3 Then
©-----------------------------------------------------------------------
©Here is where it's showed as the error when I run the "program"
: newton4(number+a,15,root)→root
©-----------------------------------------------------------------------
: Disp root
: EndIf
: EndIf
: EndIf
: EndFor
:EndPrgm
In the bold line I get this error: variable not defined Newton(x) Define newton4(guess,number,root)=
Func
:Local new_guess,fn,k,newt
©-----------------------------------------------------------------------
©Here is the problem....
:Define f4(x)=((f3(x))/(x-root))
©This line doesn't work at all
©-----------------------------------------------------------------------
:newt:={guess}
:For k,1,number
: new_guess:=guess-((f4(guess))/(nDeriv(f4(x),x=guess)))
: guess:=new_guess
: newt:=augment(newt,{new_guess})
:EndFor
:Return new_guess
:EndFunc
Note: newton4() is the same of newton3 which didn't any errors, and If I call f2()/f3()/f4() they are not defined...

Oh, I see. I don't think you can do that, unfortunately. You can always overwrite existing functions though. Don't know if that would help with what you're doing.
It might help, but how can I overwrite and/or create functions since Define doesn't work? //it doesn't appear as a syntax error but it don't work

Is for the nspire, I don't thing the raiz=root may help any as what I need
is to define multiple functions
such as
f1(x)
f2(x)
f3(x)
...
fn(x)
And I can't figure a way to do it...

I know it hasn't been a long time since my last post, but
as this is another subject I thought it was better to make a new one...
I was trying to make define a function again, for dont have many functions in the calculator
but I got this error: "To many recursions", and display "Define f2(x)=((f2(x))/(x-raiz))"
: If a≠grau Then
: Define f2(x)=((f2(x))/(x-raiz))
Now I was wondering if is possible to create functions like f3 ... on demand like
Define f(x)=x...
Thanks, for any help regarding this.

Suppose you have a function like Define a(Expression,[varlist],[varerror])=Func ... How can I know how many terms the user used between each [] ? I know that, if was a list such as a(expr,{varlist},{varerror})=func I could do: newMat(dim(varlist),1) but with this workaround I can't re-use the function ... as the output would be in the format[], and the input is a list ..  Thanks for read this topic, and especially if can clarify how to do this!!

How do I clean the screen using ndless 1.7 [C]?
In unix it would be: system("clear")
or system("cls") for Win NT ...
Is something like that available to ndless?
EDIT:
I didn't find anything for scanf() or gets() too,
how can I use these functions?

I'll be working on SimpleCS whatever happens, I'll have Wabbit allowed to run on my computer, so no problem about it  I'm even thinking of tranlsating SimpleCS to the Nspires' programming language, but I don't remember if there's a BASIC language in those
Yes and not, as the basic isn't the same and has less features..

with the cas+, keep in mind that there would be hardly any, or not at all any support for the model since it is a prototype pre-release model.
I won't get any support neither for my calc as TI hardly reply any e-mail [my only support is here and other forums] and isn't easy to find any retail store about calcs [except hp] down here... [It doesn't matter for my teachers which calculator I am using, and they don't provide us any app/document for calc]

fb39ca4, yes it's just for Math/Calculus as for playing/programming I have my nspire clickpad ... and the upgrade was just a thought, because they appear to be quite similar for me, as the most functions are the same in both. If you just want to do math, get an HP and learn RPN, as well as HFAA.
It's cheaper the CAS+ than an average hp50g, Well i know some RPN, but I couldn't understand what does HFAA stands for as google said: "Hardanger Fiddle Association of America" among others weirds results. Also, I don't really like hp50g, i wish there was some ti 89 titanium+ ...

Well, I was just looking at some google pages ...
and saw at least 3 Nspire CAS+ for sell in some sites [including ebay]
I know it isn't upgradable [in theory] to the new OSes
but, it still much cheaper than almost every other calculator with similar functions such as taylor() among others.
So my question is: Is it worth to pay 170 BRL =~[100 USD] =~ [80 euros] for it?
It would be for college study.
And another question, but this I think will not be easy to reply as only someone with it could try ...
How 'impossible' is to upgrade it's OS?

Very nice!
* apcalc wishes he had calculators on his Christmas tree Just one, packed under the tree would be enough for me...

I did not make the song, but if the question was for the image, then yes...

 If you do not want to click here in the image you can go to the link: http://tinyurl.com/KylloAppealYou may click, it is a very seriously appeal to the Calc community. [I am not asking for money - {I would like if you give me some, but it's not the point}]
