[[Hello world]] in Arc :

<sourcesyntaxhighlight lang="lisp">

(prn "Hello, World")

</syntaxhighlight>

</source>

To illustrate Arc's terseness, Graham uses a brief program. It produces a form with one field at the url "/said". When the form is submitted, it leads to a page with a link that says "click here", which then leads to a page with the value of the original input field.<ref>{{cite web |url=http://www.paulgraham.com/arcchallenge.html |title=Take the Arc Challenge |last=Graham |first=Paul |date=February 2008 |website=PaulGraham.com |access-date=2018-12-05}}</ref>

(aform [onlink "click here" (pr "you said: " (arg _ "foo"))]
