Introduction to Turbo Prolog by Carl Townsend (1987) is considered a classic foundational text for those learning logic programming and Artificial Intelligence (AI) during the microcomputer revolution. 

The book was specifically designed to teach Borland’s Turbo Prolog, a version of the language that famously brought AI development to personal computers.  Core Content & Structure 

The book serves as a self-teaching guide, moving from basic installation to building functional expert systems. Key areas covered include: 

Logic Fundamentals: Explains the core mechanics of Prolog, such as facts, rules, queries, and unification.

Recursive Programming: In-depth coverage of list processing and backtracking, which are essential for navigating complex data structures.

The "Typed" Advantage: Unlike standard Prolog, Turbo Prolog is statically typed (similar to Pascal). Townsend explains how to use the domains and predicates sections to make programs faster and easier to debug.

Practical Applications: Includes complete sample programs for medical diagnosis, natural language processing, and even simple gaming.

Technical Implementation: Covers graphics, sound, dynamic databases, and how to compile standalone executables for the IBM PC.  Why This Book Matters 

Accessibility: It transitioned Prolog from an academic research tool into a practical language for business and independent developers.

Structured Tutorials: The text uses a series of tutorials and exercises that allow readers to "learn by doing" rather than just studying theory.

Historical Significance: It documents a unique era where logic programming was seen as the "magical language of the future" for the Fifth Generation Computer System project.  Introduction to Turbo prolog : Townsend, Carl, 1938

About the Book

"Introduction to Turbo Prolog" by Carl Townsend is a comprehensive guide to learning Turbo Prolog, a programming language developed by Borland International. The book was written in the late 1980s, a time when Turbo Prolog was gaining popularity as a powerful and efficient language for building expert systems, artificial intelligence applications, and database management systems.

The book is designed for beginners and experienced programmers alike, providing a clear and concise introduction to the language and its features. Townsend's writing style is engaging and easy to follow, making the book an ideal resource for those new to Turbo Prolog.

Table of Contents

The book covers a wide range of topics, including:

1. Introduction to Turbo Prolog: Overview of the language, its history, and its applications.
2. Getting Started with Turbo Prolog: Installation, setting up the environment, and basic programming concepts.
3. Turbo Prolog Basics: Variables, data types, operators, and control structures.
4. Procedural Programming: Procedures, functions, and modular programming.
5. Data Structures: Lists, trees, and graphs.
6. Database Management: Working with databases, queries, and indexing.
7. Artificial Intelligence and Expert Systems: Building expert systems, rule-based systems, and decision-making applications.
8. Graphics and User Interface: Creating graphical user interfaces and interactive applications.

Significance of Turbo Prolog

Turbo Prolog was one of the first programming languages to integrate logic programming, object-oriented programming, and imperative programming. Its unique features, such as automatic memory management, dynamic typing, and a built-in database management system, made it an attractive choice for building complex applications.

Turbo Prolog was widely used in various industries, including:

1. Artificial Intelligence: Building expert systems, decision-making applications, and natural language processing systems.
2. Database Management: Managing large databases, creating queries, and generating reports.
3. Education: Teaching programming concepts, artificial intelligence, and computer science.

Although Turbo Prolog is no longer actively supported or updated, its influence can still be seen in modern programming languages, such as Prolog, C++, and Java.

3. Recursion as a Story

Recursion is the loop of Prolog. Where other books use mathematical examples (factorials, Fibonacci), Townsend uses genealogical trees. His famous "Ancestor" example unfolds over several pages:

• Rule: X is an ancestor of Y if X is a parent of Y.
• Rule: X is an ancestor of Y if X is a parent of Z and Z is an ancestor of Y. He then traces the stack manually, a practice that has saved countless students from infinite loops.

How to Ethically Find the "Introduction to Turbo Prolog by Carl Townsend PDF"

It is crucial to address the legal side of searching for this PDF. The book is out of print. The original publisher (Howard W. Sams) has been absorbed/closed, and the rights are likely diffuse.

Here is the ethical path to obtaining it:

1. The Internet Archive (archive.org): This is your best bet. The Internet Archive has scanned countless out-of-print computing books under fair use for preservation. Search for "Introduction to Turbo Prolog Carl Townsend." If available, you can "Borrow" the PDF for an hour or two to study a specific chapter.
2. Abandonware Sites (Use with caution): Some retro sites bundle the Turbo Prolog software with scanned PDFs of the Townsend book. Legally, these operate in a grey zone, but from a preservation standpoint, they are often the only remaining source.
3. Used Book Stores: For the purist, you can buy a physical copy on AbeBooks or eBay for roughly $10–$20. Scanning your own copy for personal backup is generally considered fair use.

A note on illegal uploads: Please avoid generic "free PDF download" sites that are filled with malware. They often combine random chapters or host viruses. Stick to community-vetted archives.

4. The "No Starch Press" Vibe

Before No Starch Press made programming fun, Townsend was writing with wit. His code examples are whimsical (zoo animals, pirates, detective mysteries). He believed that if you aren't enjoying the code, you won't learn the logic.

The Historical Context: The Era of Turbo Prolog

To understand the value of Townsend’s book, one must first understand the software it was written for: Turbo Prolog (later known as PDC Prolog or Visual Prolog).

Released by Borland in 1986—the same company that brought us Turbo Pascal—Turbo Prolog was a revolution. Prior to this, Prolog was largely confined to academic mainframes and expensive Lisp machines. Turbo Prolog brought logic programming to the IBM PC for a fraction of the cost. It included an integrated development environment (IDE), a debugger, and, most importantly, a compiler that produced blisteringly fast native code.

Enter Carl Townsend. A prolific author of computer books in the 80s (known for titles on dBase, Clipper, and Fortran), Townsend recognized that Prolog's syntax was alien to programmers raised on BASIC or Pascal. His book served as the perfect bridge.

1. The "Hello World" of Logic

Most Prolog books start immediately with predicate calculus. Townsend starts with the Turbo Prolog IDE. He shows you how to load the editor, fix syntax coloring (a novelty then), and run your first fact:

predicates
  likes(symbol, symbol)
clauses
  likes(ellen, tennis).
  likes(john, football).
  likes(ellen, swimming).

He then walks you through the query likes(ellen, What)—and the euphoria of the computer responding What = tennis; What = swimming.
