ReplyDeleteNice. You actually tried to create a pseudo-code for something which is pure code inside the machine! But there is a problem with your code flow: you are calling the functions within themselves! This means each function will only be called if the function itself is called. A bit strange no? take a look at the other codes here at the blog: most of them create what we can call a "chain" of functions, with one function calling the other until the whole task is terminated.
