Ok Mike thanks, I shall never again refer to the void loop (except here this one time for reference).
It is the loop function
Yes, the nesting of the for loops is an issue for me. Yes, the for loop is not yet second nature.
And yes, the flexible nature of variables and how they ping around the code is still a source of wonder.
I have not yet found any tutorials on nesting loops.
I thought that having one for loop leading to braces containing another for loop was nesting one set of code inside another, but I shall dig deeper... Um and think harder.
I'm sorry to be testing your patience, perhaps a little break is in order?
