Readers will note with some sadness that no new Modula-2 books seem to have been produced for some time. So far as is known, only one of the many authors who produced textbooks on classic Modula-2 has updated his offerings. Oberon Like Wirth's other famous language, Pascal, Modula-2 has several descendants. Oberon has a small but devoted band of followers, who will tell you that their small, well-honed systems are infinitely better than any of the other behemoths that shall remain nameless. Oberon has its own newsgroup comp.lang.oberon .
Implementations are available for most platforms, many free of charge.
Actively supported commercial Modula-2 compilers For an extensive list the FAQ should be consulted. This compiler was developed as a shareware product by Roger Carvalho but is no longer actively supported. It essentially conforms to PIM version 3, but also supports some simple and interesting OOP extensions. A Java version is expected shortly. A compiler construction toolkit named Cocktail was implemented in Modula-2 by Josef Grosch , using the Mocka compiler.
