Abstract: |
In
1967, SIMULA 67 was presented at the IFIP Working Conference on Simulation
Programming Languages. Although the exact definition of SIMULA 67 was a bit
modified during the next year, the essential properties of the first proposal
were conserved and respected. Among them, the properties declared later as
those characterizing the object-oriented programming (classes, subclasses and
virtuality of methods) were introduced, but also
other properties like (a) “life rules” of running in quasi-parallel systems
at a mono-processor computers, and (b) classes local in blocks and in
objects. Although property (a) rooted in an old practice introduced for
discrete event simulation, it was ignored in many object-oriented tools, but
– combined with the object orientation - it leads to agents. Property (b)
leads to combining simulating agents reflected in a simulation models that
could be programmed by different agents. Applications will be presented, too. |
