The first programming language for the Xerox Alto was BCPL, the language that led to C. This article shows how to write a BCPL “Hello World” program using Bravo, the first WYSIWYG text editor, and run it on the Alto simulator.

(The influential Mesa and and Smalltalk languages were developed on the Alto, but those are a topic for another post.)
