TYPED_BY

   The TYPED_BY function is a relationship function. It finds
   occurrences that have a TYPED_BY relationship between them.
   For example, if variable X is typed by INTEGER, then these two
   occurrences are in a TYPED_BY relationship. In its most common
   form, the function format is as follows:

   TYPED_BY( <type>, <typee>, DEPTH={<number> | ALL} )

   In this format, <typee> and <type> can be any legal query
   expression, and <number> is a positive integer. A typical use
   of the function is to find what is being typed by INTEGER. For
   example:

     FIND TYPED_BY( INTEGER, *, DEPTH=1)

   This query finds everything that is of type INTEGER. The TYPED_BY
   function can also tell you the items that are in some way affected
   by a given type. The type can be predefined by language elements
   such as INTEGER, or can be user defined. For example:

     FIND TYPED_BY( user_defined_type, *, DEPTH=ALL)

   This query finds all the items that are directly or indirectly
   affected by USER_DEFINED_TYPE.

   The TYPED_BY function provides the power to return the exact type
   tree you want. The full format is as follows:

   TYPED_BY( [ END=<type> ],
             [ BEGIN=<typee> ],
             [ DEPTH={<number> | ALL} ],
             [ RESULT=RESULT_KEYWORD ],
             [ TRACE=query_expression ] )

   In the previous format, <type> and <typee> is any legal query
   expression, <number> is a positive integer, RESULT_KEYWORD can
   be STRUCTURE, NOSTRUCTURE, ANY_PATH, BEGIN, or END, and QUERY_
   EXPRESSION is any legal query expression.
