The SetToDefault method sets the value of the field to its default value.

Use this method to clear the field for user input. This method also resets the HasDataChanged attribute for the field to FALSE. If the field is a CompositeField, all the component fields are set to their default values as well.

A composite field is additionally affected in that a new instance of the data object is associated with the composite field. For example:

creates a new, empty array for the table field.

To set all fields in the frame to their default value, use the following 4GL code:

This code also sets all MenuList and MenuToggle fields associated with the form to their default values. (MenuList and MenuToggle fields are the only menu fields that have default values.)
