IBM Smalltalk

Using IBM Smalltalk, you can easily extend the behavior of a VisualAge part. The following terms introduce you to some of the more common IBM Smalltalk concepts you will encounter when using VisualAge. For a more thorough understanding of this very robust programming language, refer to the VisualAge Smalltalk Library web page .

A class specifies an object, including its data and behaviors. Methods, which are called scripts in VisualAge, are executable code that implement the behavior or logic of a particular class.

A VisualAge part is simply a class with some predefined data and behaviors that enables it to be edited visually in the Composition Editor.

In IBM Smalltalk, an application is a collection of classes that provide a reusable piece of functionality. IBM Smalltalk provides a set of browsers to view and modify the applications and classes you create while developing your applications.
