The New ABL Class wizard helps you define an ABL class. You start the wizard in the workspace directory where you want to create the ABL class file. This is typically in a directory underneath the src directory for a project.

In the wizard, the package is automatically set by the location in the directory structure where you start the wizard. You must specify the class name. As a best practice, you should select the method stubs for the default constructor and destructor. In addition, you should retain the default error-handling generated by the wizard.

It is always a good practice to provide information that describes the class.

When the New ABL Class wizard ends, the class file is created in the package location in the workspace and opens in the editor.

Example

Here is an example of the code that the New ABL Class wizard generates for the Emp class. A using statement is the first statement in this file. It specifies that this class will use all the built-in classes defined in the Progress.Lang package. The block level error-handling is then specified. The name of the class is Emp and the name of the file is Emp.cls. This file resides in the Enterprise.HR package, which maps to the Server/src/Enterprise/HR directory in the workspace.

The class definition begins with the class keyword, followed by the fully qualified class name, which includes the package. The class definition ends with the end class statement. This class currently does not have any data defined. It has the default public constructor and destructor defined, but not implemented.
