A dedicated object-based language is used to describe the various components of the data-acquisition system. Each component is declared in terms of finite state machines and sequences of parametrized actions to be performed for operations such as the start and end of a run. The description, written by the user, is translated into Ada to produce a run-control program capable of controlling processes in a distributed environment A Motif-based graphical interface to the control program displays the current state of all the components and can be used to control the overall dataa-cquisition system. The SM has been used by several experiments both at CERN and other organizations. We present here the architecture of the SM, some design choices, and the experience acquired from its use.
