Oberon is a programming language created by Professor Niklaus Wirth,
the father of Pascal and Modula.
It is very Modula-like in its syntax, but offers an interesting feature
which is only recently becoming available in more commonly used development systems: exportability of procedures.
Imagine that for your program you create a PNG viewer procedure
and that you export it: any program on the system will be able to view PNG files!
That's true reusability.
Granted this is now possible on other systems
(see for example the use made by Galeon of the Mozilla engine),
but mechanisms in Oberon are far better and simpler than most of those currently in existence.
Like NeXT, Oberon can also be a complete operating system.
Free implementations of Oberon can be found on the Internet.
There is a release called Native Oberon. As it includes an operating system so it can directly boot. There is as well a version for .NET.
