ABSTRACT:
Apparatus for controlling the use of software in accordance with authorized software license limits, including a limit of the number of concurrent usages of a particular software in a computer system having one or more operator terminals and a central processor containing the software. The apparatus includes a receiver that monitors usage requests from the software in the central processor. A microprocessor based controller accesses authorized use data stored in an EEPROM. Depending on the propriety of usage requests, the controller and an interruptor and transmitter coupled to the central processor and its software prevents operation of the software and/or provides warning messages on the terminal screen.
