Real-world Programming for OS/2 2.1

Real World Programming for OS/2 2.1 is a fairly hefty book at no less than 868 pages! It is aimed at (it says here, on the back) intermediate to advanced (users or programmers?), and is meant as a PM programming how-to book. It comes with a 3.5" diskette with all the source code from the book. It even has its own installation program, and a very nice one at that. The authors encourage you to use the source code from the book in your own programs, although they do insist that enough modifications should have been made to make the code basically your own work.
