    Patent number: 4447874
    Abstract: An apparatus for enabling communication of information between processes being carried out on a computing system. Each process is assigned a control block including a specialized memory element. A process being executed modifies the state of each memory element if it discovers any information of interest to processes awaiting execution. Before the next process is executed, the memory element in its control block is tested to find out if the previously-executed process left any information of interest.
