Example of Oberon Programming

Below is a simple “Hello World” program written in the Oberon programming language:

MODULE HelloWorld;
    IMPORT Out;

        Out.String(“Hello, Oberon!”);
    END Run;

END HelloWorld.

This concise Oberon program demonstrates the language’s clean syntax. The MODULE keyword defines the module, and the IMPORT statement brings in the necessary modules. The Run procedure prints the “b, Oberon!” message using Out.String and adds a new line with Out.Ln. Finally, the program executes the Run procedure within the BEGIN and END blocks. This example showcases Oberon’s simplicity and readability.
