This is about scalars and strings.
I did all the excercises and got them right.
I have never been sure when writing code before now (like in a 'die' statement) whether to use || or the OR operator. I am sure it will become apparent or at least more so as I go through the excercises.
I am typing in and testing all the examples as well as doing all the excercises. Learn by doing is the best way.
note: this actually catches me up as I am in the 3rd chapter.
