Modifying output fields

You modify an output field by altering the data to which the command-level parameter list points.

The technique described in Modifying input fields is not suitable for modifying output fields because the results would be returned to the new area instead of the application's area, and would be invisible to the application.

In the case of an output field, you can modify the application's data in place because the application is expecting the field to be modified anyway.
