Abstract: The present invention provides a computer system, a method of creating and allowing access to a parameterized collection class and a real time process control system. The computer system includes: (1) a memory containing an operating system capable of operating on one or more parameterized collection classes, or objects, (2) a persistent data store, associated with the memory, in which a parameterized collection class is memory-mapped and (3) a processor, associated with the memory and the persistent data store, that: (a) instantiates an occurrence of the parameterized collection class in the memory, the parameterized collection class thereby becoming persistent, and (b) provides direct access by at least one routine executing in the processor to the persistent parameterized collection class, the persistent parameterized collection class surviving termination of the routine.
