I need a lesson in loops

 

Hi Forum, hoping someone might point me towards a lesson or article (on loops)

I keep getting myself into trouble with some of the basics and figure it is time I improved my knowledge in this area.

When I search the forum I find mainly examples of individuals problems.

But assume there is part of the book or documentation that explains them in their most basic form.

All help always appreciated, thanks Dave
