OS/2 Programming: An Introduction - Herbert Schildt

The purpose of this book is to give you a "jump start" into the world of OS/2 programming. OS/2 is a big program, and the ways that you, the programmer, can interact with it are numerous and varied. This book will help you understand quickly the essence of OS/2.

The impact of OS/2 is not to be underestimated. OS/2 has done for microcomputer operating systems what the original IBM PC did for microcomputers: in one bold stroke it has defined a new, more power-ful computing environment. What makes OS/2 so exciting is that it is the first multitasking operating system designed specifically for the personal, single-user computer. Although microcomputers have been able to run multitasking operating systems such as UNIX for several years, the results have never been entirely satisfactory, partly because the porting of a multiuser, multitasking operating system to a single-user, highly interactive environment generally produced the worst of both worlds: slow response time combined with an old, TTY-based interface. OS/2 maintains the highly interactive nature of the personal computing environment while allowing greater through-put by means of multitasking. In the first part of this book you will see how this near-magical combination is achieved.

As you will see in this book, there is little in OS/2 that is difficult to grasp or use. However, OS/2 is so large that it is sometimes hard to see the larger view. For example, OS/2 contains several hundred different system services! As you begin to learn to program for OS/2, it may seem hard to pull all the pieces together, but as you become more experienced, the logical design of OS/2 will become apparent.

This book can help you achieve that "view from a height".

OS/2 opens the doors to a whole new world for programmers. Fully harnessing OS/2's capabilities will allow you to create highly efficient and powerful programs, the likes of which could never be seen in either a DOS or UNIX-like environment. OS/2 is the platform on which the next generation of applications will be built.
