Oberon

Oberon is a general-purpose programming language created in 1986 by Niklaus Wirth at ETH Zurich. It is the latest member of the Wirthian family of ALGOL-like languages, which also includes Euler, Algol-W, Pascal, Modula and Modula-2. Oberon came out of a concentrated effort to increase the power of Modula-2, the direct successor of Pascal, while at the same time reducing its complexity. Its principal new feature is type extension of record types, which lets a programmer build new data types on the basis of existing ones and relate them to each other, a deliberate departure from the dogma of strictly static data typing. The language also supports pointers, assignment with the colon-equals operator and multi-line comments.

Oberon is a general-purpose programming language created in 1986 by Niklaus Wirth, the last member of the Wirth family of languages that began with Algol W and continued through Pascal and Modula-2. Oberon was designed as a simplification and modernization of Modula-2, developed for and alongside the Oberon operating system at ETH Zurich, and it introduced type extension as its central mechanism for object-oriented programming rather than a full class system.
