Oberon3

Oberon-3 is a member of the Oberon programming language family. It is a revised version drawn from Oberon and Oberon-2, designed to preserve the strengths of the original language—small size, clear syntax, and a modular program structure—while streamlining the feature set and clarifying semantics. It was developed by Niklaus Wirth and Hanspeter Mössenböck as part of ongoing research into compact languages for teaching and systems programming.

Design and features: Oberon-3 emphasizes static typing, strong module boundaries, and a straightforward syntax intended to facilitate readability and correctness. The language retains Oberon's module system and a simple type model, and it avoids some of the more complex extensions found in later variants. It aims to be portable across hardware and operating systems with minimal runtime support.

Implementation and usage: Oberon-3 has limited adoption compared with Oberon and Oberon-2, existing primarily in academic projects and among language enthusiasts. Several hobbyist compilers and tools have been developed, but there is no widely used official standard or mainstream toolchain. The language is typically used for teaching concepts of modular design, type safety, and compiler construction within the Oberon ecosystem.
