The more important legal questions which have been extensively discussed by Soviet commentators are those involved in the development of the legal framework for the creation of an au tomated system of management.

The planned economies of the Soviet Union and Eastern Europe have long experience in the development of mass production of industrial products.

A number of special rules apply to the supply of computers and control systems. The most important use of microprocessors is as controllers for a wide variety of industrial and consumer goods, for instance computer terminals and washing machines.
