This book is a comprehensive tour of all the essential elements of the  Progress 4GL. The Progress 4GL remains by far the most powerful and  comprehensive language for developing serious business applications.  Combined with the Progress RDBMS(tm) database and the other components  of the Progress OpenEdge(tm) product family, the Progress 4GL can  support you in building and deploying your applications in ways that are  matched by no other environment today. By the time you complete this  book, you will be competent to build thoroughly modern applications that  take advantage of most of the language's features. And you will use the  language to build powerful business application logic, not just the toy  demonstration windows you find in other language tutorials. Progress is  not a toy. It's a tool for serious developers who have serious business  problems to solve.      This book is written for two different kinds of audiences. The first  group consists of existing Progress developers who might have created  applications in earlier releases of the product, when many of the more  recent extensions to the language were not yet available. If you are  already experienced in the 4GL, you will find some of the material,  especially in the first couple of chapters, familiar. Feel free to skim  through those sections quickly, but you should not skip even the first  chapters altogether to avoid missing anything-there are changes and  enhancements to the language at every level.      The second audience for this book consists of people completely new to  Progress. For those of you in this second group, you should take the  time to learn enough about the language to understand some of the many  ways it can help you in your development work. You probably need to have  a background in some other programming language to catch on to Progress  quickly, because the material might come at you fast and furious.  Despite its many extraordinary and unique features, the Progress 4GL is  basically a procedural programming language with most of the same  constructs common to almost all such languages.
