Chapter 9 Learning Additional Screen Techniques You have now been introduced to most of the fundamental areas of HP ALLBASE/4GL. This chapter and the following chapters will show you how to extend your application even further. As well as using methods you have already seen, these chapters introduce a number of new techniques and new items. The style of these lessons differs from the earlier lessons. Each keystroke is no longer fully defined for you. In most cases you're only given a description or diagram of the completed item. It's up to you to use the appropriate facilities to create the item. This chapter draws your attention to any new techniques that are introduced. In addition, it discusses the purpose of the items you create. We recommend that you take your time going through these lessons. Look back over what you have already done, use the developer menu chart, and if necessary, use the HP ALLBASE/4GL Developer Reference Manual for more detailed information about the items being used. Throughout these lessons, we suggest that you create your own descriptions on screens that have description fields.
