nonstructured_relationship_expression

   A relationship query (such as CONTAINED_BY, CALLED_BY, CALLING)
   which requests that structure information be excluded. You can
   specify RESULT=NOSTRUCTURE, RESULT=BEGIN, or RESULT=END as one
   of the parameters to the relationship function. If you specify
   RESULT=BEGIN or RESULT=END, this is displayed like any query
   which does not have a relationship function. If you specify
   RESULT=NOSTRUCTURE, this is displayed like any query which does
   not have a relationship function, but has all the occurrences that
   would be present if the structure were present.
