Help with a TI-83 program

Mantrid

I can't for the life of me figure out why this isn't working. This is a proof-of-concept program that will later be adapted to the whole alphabet, and some symbols. Its meant to take a 32 digit long number and convert it into 16 characters.

Code is as follows:

<!--c1--><div class='codetop'>CODE</div><div class='codemain'><!--ec1-->
16->B
0->X
Input A
Goto A
Stop
Lbl A
If B=0
Then
Stop
Else
B-1->B
X+1->X
int(A/(100^B))->A
If A=10
Then
Output(7,X,"A"
Goto A
Else
Output(7,X,"B"
Goto A
Stop
<!--c2--></div><!--ec2-->

I haven't made an TI-83 programs recently, but Im not sure you can use the same letter for a label as you are using for a variable, though I may just be dumb.

Also, by "not working" what exactly doesn't it do? Does it just give the good 'ol syntax error or something else?

Mantrid

Hmm, when I change the intial value of B to 15, it gets slightly closer to working.

Anyway, what it does it, if the 32 digit number starts with 10, it'll output A, and then nothing but Bs. And when it leads with something other than 10, it outputs only Bs. Thats how it should work, sort of.

To clarify:

Input: 10555555555555555555555555555555
Output: ABBBBBBBBBBBBBBB

Now, when I input 10105555555555555555555555555555
I should get AABBBBBBBBBBBBBB

Or, when I input 10555555555555555555555555555510
I should get ABBBBBBBBBBBBBBA

But I don't. It decodes the


Holy crap I just figured it out.

Mantrid

Okay, no I didn't. I'm closer now.


Revised code:

<!--c1--><div class='codetop'>CODE</div><div class='codemain'><!--ec1-->
15->B
0->X
Input A
Goto A
Stop
Lbl A
If B=-1
Then
Stop
Else
B-1->B
X+1->X
int(A/(100^B))->N
A-(N*100^B)->A
If N=10
Then
Output(7,X,"A"
Goto A
Else
Output(7,X,"B"
Goto A
Stop
<!--c2--></div><!--ec2-->

Now, its doing what its supposed to, for a bit. It seems that after its decoded 7 characters, it stops.

Thus,

Input: 10101010101010555555555555555555
Output: AAAAAAABBBBBBBBB

But also

Input: 10101010101010555555510555555555
Output: AAAAAAABBBBBBBBB

Or even

Input: 10101010101010101010101010101010
Output: AAAAAAABBBBBBBBB

I'm not certain, but I seem to recall there being a limit on numerical input with the Ti-83 having to do with significant digits. IIRC, it will only keep track of a 10 digit number before losing precision.

Mantrid

God, if only they let you store things besides numbers in a list, this wouldn't be a problem...

[edit] nevermind >_< how do you delete a post again?
And I spent the time typing all that into my ti-83, too.

That code got me this
