Chapter 15 Working with User Objects
About this chapter
One of the features of object-oriented programming is reusability:
you define a component once, then reuse it as many times as you
need without any additional work. One of the best ways to get reusability
in PowerBuilder is with user objects. This chapter describes how to
define and use user objects.
