This book is an introductory tour of some of the essential elements of ABL (Advanced Business Language). By the time you complete the tour, you will be competent to use ABL to build powerful business application logic, not just the toy demonstration windows you find in other language tutorials. ABL is not a toy. Rather it is a tool for serious developers who have serious business problems to solve.
There are a lot more specifics to many of the language statements, keywords, and options than this book covers. Therefore, you should always refer to the product documentation for more information. Where the language is concerned, you should refer to OpenEdge Development: ABL Reference. This book has a complete description of all ABL methods, attributes, and events as well as an alphabetical listing of all the language keywords. Always look to it for more details on any topic covered in this book.
