Hello thanos1983,

I was not aware that you can call the same subroutine inside the actual subroutine.

This is a very important concept in computer science called recursion. It’s one of the key elements of the functional programming paradigm (think Lisp, Scheme, Haskell, ...), but is by no means limited to that paradigm. In fact, it’s something every programmer needs to know. Here are some references:

Hope that helps,
