Chapter 7 Learning More Features
In Chapters 1 through 6, you learned how to develop a basic application
that uses a process, a screen, a function, and a report. Together, these
items allow you to enter data into the product file, and to produce a
simple report of the data contained in the file.
The four lessons in this chapter will show you how to modify this
application so that it offers more functionality and user feedback.
This chapter will show you how to use the appropriate HP ALLBASE/4GL
screens to add the following items to the training application:
* Storage items such as:
* Variables.
* Constants.
* Application titles.
* Messages.
* Validation ranges.
To use these features, you will learn how to expand the logic blocks that
you have already written and how to write additional logic blocks. You
also will learn how to modify one of the existing field specifications.
Working with these features will give you additional practice in using HP
ALLBASE/4GL and help you learn how to use more complex procedures for
developing applications. If you do not understand a concept presented in
these chapters, check your Developer Reference Manual.
