Title: Good Book, But The Code Is Only Partially Object Oriented
Review: It is a good book and its implementation of a Pascal compiler functions fine, but I didn't like the way the code was only partially object oriented. It's hard for me to understand why the author went to the trouble of making 90% of the code object oriented and then used some global variables that should obviously be members of some of the classes. Other than that, the book was very easy to understand.
Is the review positive or negative?
