Oberon is the modern successor to Nicolas Wirth's Pascal programming language. It's a modern procedural language with an emphasis on modules. The compiler is delightfully easy to install and use.

Obligatory "Hello world":

code:

module Hello; IMPORT Out; BEGIN    Out.String("Hello world!"); Out.Ln END Hello.

With a procedure:

code:

MODULE Hello; IMPORT Out; PROCEDURE SayHello; BEGIN    Out.String("Hello"); Out.Ln END SayHello; BEGIN    SayHello END Hello.
