Thank you very much, Jaques, I agree with everything you say. The best thing that you can do to contrast an idea is to paint with a pencil what you have understood to see if it is similar to what the other person thinks...

Good Times the 80s, by the way, I remember that at the end of the 80's I was with my new ZX spectrum at home, I was still very young but I enjoyed a lot trying to hack the games using basic or assembler, but without understanding what I was doing.
