Problem Reading EP3 ItemAll

[soryjero]

i have some advances.

 

I have guessed that the piece of code i say is after some C2 but i am not sure about what value of last item i have to check to know if after last item read go piece of code or is another item.

I also have guessed all the pieces of code dont have the same lenght so i also would like to know how to know the length of the code.

 

Thanks in advance.
