USING AN ENABLE APPLICATION
ENABLE Display Screens
The edges of the screen form a box around the record (or records)
displayed by an application, which is referred to as the
outermost box. When an application displays records for more
than one file, it shows other boxes nested within this outermost
box. Figure 8-3 shows the screen produced by an application that
displays records from three files. These records contain
information about the divisional branches of a company, the
employees who work for each branch, and the type of insurance
coverage that each employee has.

Figure 8-3. Sample Screen With Nested Boxes
In Figure 8-3, the outermost box displays the fields for a
"branch" record. Nested within it is a box that displays the
fields for an "employee" record. Because the "employee" box is
completely contained within the "branch" box, the "branch" box is
called a containing box (as well as the outermost box).
Since the "employee" box is nested within the "branch" box, the
"employee" box is called a nested box. The employee box contains
another box--the "coverage" box. Because the "employee" box
contains the "coverage" box, the "employee" box is a containing
box as well as a nested box. The "coverage" box, which does not
contain another box, is simply a nested box.
