All from the perspective of users. Like getting help from someone senior.
This book organizes all the examples well and explains almost line by line.
Yet, it is all focused on programming, unlike The Little SAS Book, which is more focused on explaining how things work in SAS. It talks about more advanced materials than The Little SAS Book.
Thus, it should be more useful as a working companion. If you really want learn SAS well, maybe you should start from The Little SAS Book and then this book. In fact, I use this book to review and I am going to read The Little SAS Book again to complete this review. It works perfect for this use. You can start slowly and then just read the codes and look for explanations for any questions you may have.
