One thing you need to know before dive deeper into a programming language is printing "Hello world!" on the screen. So is Dinfio. To print "Hello world!" in Dinfio, you can code like this:

start
    writeln("Hello world!")
stop

In Dinfio, pair of keywords start and stop is optional—just a sweetener. So you can simply code:

writeln("Hello world!")
