Once a value has been assigned to a variable, you can reference
the variable anywhere in your HTML document. In the following example, a
value is assigned to
$foo and later
<html><body> #set( $name = "Velocity" ) Hello $name World! </body></html>
The result is a web page that reads
Hello Velocity World!
To make statements containing VTL directives more readable, we encourage you to start each VTL statement on a new line, although you are not required to do so.
