FullName Attribute
Data Type: varchar(256)
4GL Access: R
The FullName attribute contains the fully expanded name of the field object.
The fully expanded name of a field is its name as you would use it if you were referencing the field using the field function.
This name differs from the Name attribute only if the field is a child of one or more composite fields. For example, assume that you have a subform named emp_data that has a child field called eaddress. To refer to the subform with the field function, you would use:
field(emp_data)
For the subform, emp_data is the value in both the Name attribute and FullName attribute. To refer to the eaddress child field, you must use:
field(emp_data.eaddress)
For the child field, the Name value holds eaddress and the FullName attribute holds emp_data.eaddress.
