DEC DATATRIEVE has a Context Searcher. If it is enabled, it will
       attempt to find a context for the fields in a PRINT statement
       where the context is left incomplete by the user. Because
       incomplete context might be an error, a warning message is
       printed when the Context Searcher completes the context for the
       user.

       The Context Searcher knows how to generate inner print lists for
       records related in hierarchies or through Oracle CODASYL DBMS
       sets. The following statement normally results in a context error
       for "KID_NAME".

       PRINT FATHER, KID_NAME OF FAMILIES

       With the Context Searcher enabled, KID_NAME is found in the
       occurs list of FAMILIES. The Context Search completes the context
       as if you had typed:

       PRINT FATHER, ALL KID_NAME OF KIDS OF FAMILIES

       The Context Searcher is enabled with the SET SEARCH command, and
       disabled with the SET NO SEARCH command.
