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.
