      utility prompts you with a menu displaying the current primary
      attributes of your FDL file. After you select a primary
      attribute, the Edit/FDL utility prompts you with another menu
      displaying the secondary attributes for the selected primary
      attribute and asks which secondary attribute value you want to
      change.
