Abstract :
This paper proposes a compatible extension of PL/I as a general-purpose process-control language which makes analog and digital real-time variables available in essentially the same manner as conventional PL/I variables. Provisions are made for handling external interrupts and scheduling of tasks, including periodic tasks and groups of tasks. Implementation problems are discussed.
