What is wrong with this pseudo-code?

Someone who is following the software has seen that I have asked something about pseudo-code some hours ago here if you want to follow the context)

Well, I need to make a pseudo-code in English that will be the basis for implementing this code in Java, C # and C ++, Javascript and other languages ( some already implemented ).

So I ventured to do this pseudo-code, but I do not know if it is correct, can you tell me how to do it to make it more up-to-date and consistent with reality? That's right? What to change?
