This book represents great news for thousands of DOS-based C programmers! Now you can expand your programming skills to write programs for the OS/2 2.1 Presentation Manager without recording all your applications from scratch. Using the development of a four-in-a-row genre game (Dr. Plopper's Revenge) as an example, this important book will show you how easy it is to port C code written for DOS to OS/2's increasingly popular graphical environment. Step-by-step explanations from the book guide you quickly and easily to the OS/2 PM and teach you how to write platform-independent code that works in both DOS and OS/2. Playing the game provides hands-on learning that's fast and fun! Up-to-date for OS/2 2.1 and the new Borland C++ compiler for OS/2, this book comes complete with a disk that includes the code for both the DOS and OS/2 PM versions of the sample game program.
