?Did you read the "Introduction" Section?

With Literary Novels, one doesn't need to read the "Preface" Sections (those Sections that precede Chapter 1).

With Reference Books like "VBScript" and "Jane's Book Of Ships", one does need to read the "Preface" Sections (those Sections that precede Chapter 1) to have a better understanding of what is being communicated within the Reference Book being read.

This is true regardless of one's Programming Skill Level.

I have Beginner Code Books for various Y2K+ Computer Programming Languages like C++.

Even though I can't write C++ Code, looking at C++, I can get a general drift of what the C++ Code is doing.

C++ uses a lot of "Black Box" Coding.

HTML & Web Coding also uses a lot of "Black Box" Coding.

"VBScript" won't help you to understand, or to crack, "Black Box" Code Sequencing.
