VMS Help SCA, SCA Topics, Glossary, nonstructured_relationship_expression  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    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.
