Oberon is a general-purpose programming language created in 1986 by Niklaus Wirth and the latest member of the Wirthian family of ALGOL-like languages (Euler, Algol-W, Pascal, Modula, and Modula-2). Oberon was the result of a concentrated effort to increase the power of Modula-2, the direct successor of Pascal, and simultaneously to reduce its complexity. Its principal new feature is the concept of type extension of record types: It permits the construction of new data types on the basis of existing ones and to relate them, deviating from the dogma of strictly static data typing.
