Oberon-2

Oberon-2 is a refinement to Oberon programming language, which adds the FOR loop and type bound procedures, which is to Oberon, what classes are to other object oriented programming languages. It was developed at ETH-Z�rich by Niklaus Wirth and Hanspeter M�ssenb�ck, who is now at Institut f�r Systemsoftware (SSW) of the University of Linz, Austria.

A superset of Oberon-1, developed by H. Moessenboeck in 1991 to add object-orientation. Oberon-2 was a redesign of Object Oberon. It included type-bound procedures (equivalent to methods), read-only export of variables and record fields, open array variables, and a "with" statement with variants. It reintroduced the "for" statement.

There is an Oberon-2 Lex scanner and Yacc parser by Stephen J Bevan of Manchester University, UK, based on the one in the M�ssenb�ck and Wirth reference. Version 1.4.
