Ken:

You can subclass the native cursor and dataenvironment objects to customize their behavior. These classes need to be created in a PRG file since the Class Designer doesn't support these objects.

For example, you can create a base cursor class with custom methods and properties that handle your data manipulation tasks and other things like managing keys, validating data, etc. Then you can subclass these base objects and add them to your custom dataenvironment classes. Doing this, saves a lot of coding.
