Knowledge Handling
==================

This chapter focusses on the programming interface
offered to the knowledge engineer to access and   
modify the knowledge at inferencing time.

Documentation of the original Babylon2 syntax is
avoided. Please refer to the literature listed in
case of using Babylon2 stylus.

The organisation of this chapter is close to
chapter 7 of the babylon3 documentation.    

1) Presentation of SETs
2) misc. knowledge handling functions
3) slot-value manipulation (BQL uses them)
4) operations on SETs
 
INFORMATION: Functions, which expect instances as
            arguments, can operate with instance
            names and instance objects.
