VisualAge includes IBM Smalltalk, a powerful object-oriented language that you can use to extend your application logic. In VisualAge, a script is a series of IBM Smalltalk statements that implement an action for a part.
You create and edit scripts using the Script Editor, which gives you direct access to the IBM Smalltalk language. Scripts are associated with the parts in which they were created. VisualAge enables you to organize the scripts you write into categories.
