This chapter takes you through the complete development of an ABF application, from starting ABF through running the finished program. It describes all the components of an ABF application and tells you how to create, examine, and modify them. It presents ABF frames in the order in which you use them as you develop an application, and covers the purpose, fields, and menu options of each frame, as well as directions for using it. (The Applications Catalog and Create an Application frames are described in Overview of Tools and Languages.)

As you go through this chapter, see the sample instructions in ABF Development Example. Together they help you plan your own applications.

See the 4GL part of this guide for more information about using 4GL to enhance all the components of your application.
