Editing Rebol (section)

===Ease of use===
One of the Rebol design principles is "to do simple things in simple ways".<ref name="RD" /> In the following example the ''Visual interface dialect'' is used to describe a simple [[Hello world program]] with a graphical user interface:

<syntaxhighlight lang="smalltalk">view layout [text "Hello world!" button "Quit" [quit]]</syntaxhighlight>

This is how a similar example looks in R3-GUI:

<syntaxhighlight lang="smalltalk">view [text "Hello world!" button "Quit" on-action [quit]]</syntaxhighlight>
