[tom234]

The error is in ""M; dont know why?
anyone know why?


EXPORT CESAR()
BEGIN
local n;
LOCAL S,M,K;
””M;
//The user is asked to enter the encrypted word
INPUT(n,”Insert in quotation marks”,”Encrypted word”);
SIZE(n)S;
FOR K FROM 1 TO S DO
//This time we shift by 3 letters backwards
M+CHAR(ASC(MID(n,K,1))-3)M;
END;
PRINT(M);
END;

Hi,
The arrows (sto) are missing, the quotation marks are not the right ones (maybe because of your PC keyboard), and the INPUT command is used the wrong way to input strings.
Where did you find this example?

Here is my proposed correction:

Code:


EXPORT CESAR()
BEGIN
//local n;
LOCAL N,S,M,K;
""▶M;
//The user is asked to enter the encrypted word
INPUT({{N,[2]}}, "Insert without quotation marks", "Encrypted word");
SIZE(N)▶S;
FOR K FROM 1 TO S DO
//This time we shift by 3 letters backwards
M+CHAR(ASC(MID(N,K,1))-3)▶M;
END;
PRINT(M);
END;

No, i suspect the font is not embedded/installed and whatever you are viewing with shows nothing for unknown characters.

Your line is see as input in HP Prime for Alegerbra and in other programs like dist2:
INPUT({{N,[2]}}, "Insert without quotation marks", "Encrypted word");

Are only empty lists allowed?

Yes: { }
No: [ ] (empty vectors)

why would HP allow wrong computer code that does not work in their instruction books?

[Tim Wessman]

It is not an HP book nor site.

Talk to the author.

Ty

are there any publications by HP that show the proper syntax for programming language?

You will find useful information within the user guides and tutorials here (note that not all is official HP) :

Try also pressing the HELP button, it is really useful.

There are also a lot of built in progam examples in the calculator itself ready to load in and run/study. In the "New" screen when making a program, press "Example" to pick one.
