ABF Development Example
This chapter takes you through the steps in developing a sample application with ABF. To keep the presentation brief and clear, the Sales Entry Application contains a simple example of each major screen type. The application includes the built-in procedures beep() and help_field().
Follow the development process presented here to see how you can use ABF, with a minimal amount of 4GL coding, to produce a functioning forms-based application.
• The first part of this chapter describes the application's frames and capabilities.
• The second part of the chapter gives detailed directions for creating the application frames.
As you move through this chapter, see the detailed descriptions of the ABF frames and menu operations in
Building Applications. This chapter avoids repeating the material in that chapter, where possible.
For more information on using 4GL in ABF applications, see the 4GL part of this guide.
