- Oberon is the special systems and application programming language developed
- by Prof. Wirth as a successor to Modula-2. It incorporates the idea of "type
- extension" whereby new types can inherit features of previously-declared types.
- This is not quite object-oriented, but it's close, especially with procedure
- pointers in records. It is designed to be 100% type-secure, and has facilities
- for testing the safety of various types of casts. It incorporates a garbage
- collector, as well, Prof. Wirth having finally decided that new/dispose simply
- required too much of the programmer. It inherits Modula's module concept, but
- does not support local modules, nor many other features of Modula-2 that do not
- fit the type-extension paradigm, including enumerations and sets of anything
- but <wordsize> bits. The language is implemented in around 4000 lines of
- Oberon for Dr. Wirth's new National Semiconductor 32K-based workstation.
-
- Oberon is available for anonymous ftp via neptune.inf.ethz.ch (129.132.101.33).
- Several ports are provided, including one for a Sparc.
