SIMULA I
     
         SIMUlation LAnguage.
     
        An extension to {ALGOL 60} for the {Univac 1107} designed in
        1962 by Kristen Nygaard and Ole-Johan Dahl and implemented in
        1964.  SIMULA I was designed for {discrete simulation}.  It
        introduced the {record} {class}, leading the way to {data
        abstraction} and {object-oriented programming} languages like
        {Smalltalk}.  It also featured {coroutines}.
     
        SIMULA's philosophy was the result of addressing the problems
        of describing complex systems for the purpose of simulating
        them.  This philosophy proved to be applicable for describing
        complex systems generally (not just for simulation) and so
        SIMULA is a general-purpose object-oriented application
        programming language which also has very good discrete event
        simulation capability.  Virtually all OOP products are derived
        in some manner from SIMULA.
     
        For a description of the evolution of SIMULA and therefore the
        fundamental concepts of OOP, see Dahl and Nygaard in ["History
        of Programming Languages".  Ed. R. W. Wexelblat.
