      This paper presents a technique to implement control of complex
      user interface dialogues. It is based on event-driven control flow
      specifications described by a deterministic statechart dialect.
      With the aid of this technique the dialogue control is expressed
      in terms of a statechart. This statechart is then converted into
      tables handled by a run-time commented in greater detail.  The
      execution of the run-time driven by those tables is equivalent to
      the behaviour specified by the underlying statechart. The
      resulting system calls specific application functions in response
      to user interactions mapped to events by the presentation
      component.  The application is seen as a set of subroutines which
      can be invoked during the interaction with the user. The use of
      the proposed technique frees the programmer from the
      implementation of complex control aspects.  The way of how to
      construct these statechart dependent tables, their use by the
      run-time, and the way semantic actions are attached are
      illustrated by a small example of a reative system which
      highlights mainly dialogue control aspects.
