Hello GrandFather,

First of all thank you for your time and effort reading and replying to my question. You are right, always I am getting into these stupid details. I guess I was more curious to found what function to use when. Who care for a few bytes. The important part as you said first of all, is to be able to understand what it does and then all the rest.

Thanks I guess I will go with named routines, simple as that.

Local subroutine, I call it because the author of the tutorial Creating Nested Functions was calling it like this.
