How to capture the Frame Name during run time

Is there any API or through URL,so that I can capture "frameName" during run time.
Because load runner is recording dynamic frameName whenever I record script.

 web_button("BUTTON", "ID=pt11:cb2", "FrameName=test", 
  ACTION, "UserAction=Click", 
  LAST);

 web_edit_field("pt11:it1", "FrameName=test", 
  ACTION, "SetValue=12345", 
  LAST);
