CALLING

   The CALLING function is a relationship function. It finds
   occurrences with the CALLING relationship between them. For
   example, if routine A is calling routine B, then these two
   occurrences are in a CALLING relationship. In its most common
   form, the function format is as follows:

   CALLING( <callee>, <caller>, DEPTH={<number> | ALL} )

   In this format, <callee> and <caller> can be any legal query
   expression and <number> is a positive integer. A typical use of
   the function is to find those routines which are calling some
   specified routine call. For example,

     FIND CALLING( abc, *, DEPTH=ALL )

   This query finds the full call tree above ABC, where ABC is some
   routine in the SCA database. In other words, find all the routines
   that are directly or indirectly calling ABC.

   The CALLING function provides the power to return the exact call
   tree of interest. The full format is:

   CALLING ( [ END=<callee> ],
             [ BEGIN=<caller> ],
             [ DEPTH={<number> | ALL} ],
             [ RESULT=RESULT_KEYWORD ],
             [ TRACE=query_expression ] )

   In the previous format, <callee> and <caller> is any legal query
   expresion, <number> is a positive integer, RESULT_KEYWORD can be
   STRUCTURE, ANY_PATH, BEGIN, or END, and QUERY_EXPRESSION is any
   legal query expression.
