Abstract

Oberon-2, the latest Prof. N. Wirth language design, supports object - oriented (OO) programming through an original record type extension mechanism. The language is expected to gain a growing acceptance both in the academic and industrial worlds. This short note aims to make a critical evaluation of Oberon-200 facilities by showing how the current language definition can be too restrictive in the building of usual type hierarchies like those allowed, for instance, by C++. A minor extension is suggested which improves the effectiveness of Oberon-2.
