The PropertyChanger utility traverses the source of a database application, examining each field in every frame in all selected applications and makes defined changes. Some changes are already pre-defined in the PropertyChanger and provide the standard upgrade and restyle support described previously.

Because the part of the utility that processes fields and frames is available as annotated 4GL source code, you may make additional changes or replace the pre-defined ones. For more information, see Customize the PropertyChanger.
