CREATING AND RUNNING A MULTIFILE APPLICATION
Associating and Linking Boxes
Sometimes the links that you can establish will determine the
level at which a box must reside. Suppose that your application
uses a box named "dept-box" as well as two of the boxes
("employ-box" and "depends-box") described earlier. Suppose
further that you can link "dept-box" to "employ-box" but you
cannot link "dept-box" to "depends-box." Depending on the
purpose of the application, you could identify the levels shown
in Figure 5-8.
