for loops and setarray

[Xbob42]

I'm probably not the first to ask about these. I'm trying to learn about for loops and setarray (arrays or something).

Will anyone be nice and willing to post an extremely small script that does something and add an explanation (comments) alongside them so I can read it and hopefull get a better understanding of them.

I've tried to search through the old threads, but I didn't find anything really useful for what I was looking for.

I'll be very greatful and give many thanks to whoever could help me to understand them.
