From the reviews: "The primary programming language topics covered are basic imperative constructs, functions, semantics, recursion, data types, exceptions, and objects. It is clear and easy to read, with nice exercises ... . it is written at a good level for undergraduate students." (M. D. Derk, ACM Computing Reviews, June, 2009) "As stated in the title, this book focuses on the principles of programming languages. ... Numerous exercises are included, ranging from simplistic to relatively complex. ... This book would be of most help to those who already know exactly what they are looking for and would like to see an example of that construct. Summing Up: Recommended. Graduate students through professionals/practitioners." (M. B. DuBois, Choice, Vol. 47 (6), February, 2010)
