You can download the file and open the .8xp program with software called TI Connect CE. This software will also allow you to transfer the program to your calculator with the direct USB cable.

Here is the source code anyway:

I made a few trivial optimizations, but didn't change anything structurally.

There is no KcrHome command. Check to make sure your code is typed in correctly. :)

It reads "Delvar KClrHome" he forgot to put the 'l' in ClrHome. Hope that helps.

Eternity; "Did I tell you stories 'bout the saints of old? Stories about their faith?"

Look, Even if this thread was active in April 2016, There is some things the creator needs to know.

There is still optimization that can be made, either by using the sub( command or by turning the:

```
:If 12=L2(K
:Then
:Output(7,K,C
:End
```

This can be optimized to *without* the End and Then commands.

I have heard, using Ans is quicker than the actual variable itself.

So,

```
:L2(K
:If Ans=12
:"C
:Output(7,K,Ans
```

It could actually be

```
If 12=L2(K
Output(7,K,C
```

-Vie la vie que la vie est bonne -quod est bonum vitae in vita

-lebe das Leben, weil das Leben ist gut -vivere la vita, perché la vita è buona
