FormField Class
Note:  The FormField class is used for classification only.
This class is the highest-level object for all form objects in the frame (it does not include the menu objects). This class contains much of the size and bias information associated with the field.
To access the FormField attributes for fields created in Workbench, you must use the field function. This is because the name given to the field actually represents the data associated with the field within the 4GL script. To access the field's data, use the name directly.
In contrast, to access the FormField attributes of a field created dynamically, you can reference them directly using variable names. This is because the name given to a dynamically created field represents the FormField object itself, not its associated data. To access the field's data, you must use the methods GetFieldValue (see GetFieldValue Method) and SetFieldValue (see SetFieldValue Method) defined for the FieldObject class.
You can set many of the attributes of FormField at runtime to modify the behavior of the frame dynamically.
