This invention relates to variable control exemplified by selectively invoking one or more inference engines in an expert system. Such variable control amounts to switching among networked tasks in which the networking relations are superimposable upon external modules. Expert consultation systems involve organized problem-solving knowledge in dialog relation with a user. Included among the components are a knowledge-focusing object and an explicit control language. The knowledge-focusing object is termed the Focus Control Block (FCB). Each FCB consists of a set of properties which gives information about how to control problem-solving processes and which states explicitly how objects, such as parameters and rules, will be used in an expert system.
