Defining a Screen Display Using MAPC › Summary

Summary

In this chapter, you defined a screen, or map, by using MAPC. XXXMAP contains two types of fields:

• Literal fields— At runtime, literal fields display literal strings.
• Variable fields—At runtime, variable fields display stored values and allow users to input values.

You defined the layout of fields on the map:

1. You named the records that would appear on the map.
2. You named the elements of those records that would be displayed.
3. You used the autopaint facility of MAPC to create a map automatically.
4. You modified the placement of the elements and added further literal and variable fields.
5. You edited fields by using the Field Definition and Literal Definition screens. You associated each map variable field, not already associated, with a record element or special system field. You also provided additional field characteristics, such as a pad character.

A map can be used by any number of dialogs. For example, XXXMAP is used by dialogs XXXDADD and XXXDUPD in the sample Department application. You will define these dialogs in Chapter 9.
