Most books on programming start out with an example of how to display a string, "Hello World." We wanted to do the same thing in NOLOH to give you an idea just how concise NOLOH programs can be and still be completely understandable.

We've included two versions of a Hello World application. The first version is uncommented so you can read through it without anything getting in your way. The second version is commented so you can get a clearer idea of how NOLOH programs are constructed.

Uncommented Version

<?php
require_once("NOLOH/NOLOH.php"); 
 
class HelloWorld extends WebPage
{
    function HelloWorld()
    {
        parent::WebPage('My First NOLOH Application');
        System::Alert('Hello World');
    }
}
?>

Commented Version

<?php
//Path to the NOLOH kernel
require_once("NOLOH/NOLOH.php"); 
//Declare a HelloWorld class that extends the built-in NOLOH WebPage class
class HelloWorld extends WebPage
{
    //Declare a Constructor for the HelloWorld class
    function HelloWorld()
    {
        //Call the parent WebPage Constructor passing the title of the web page
        parent::WebPage('My First NOLOH Application');
        //Call NOLOH's built-in Alert function and pass it a string to display
        System::Alert('Hello World');
    }
}
?>
