In the programming world, a "Hello, World!" program This is a link to a Wikipedia article is used to illustrate basic syntax using a very simple program. The "Hello, World!" program in Nasal would look like this (run this in the Nasal Console):

print("Hello, World!");

This will print the string Hello, World! into the console.

To show a message inside the FlightGear window using a GUI tooltip instead, use the following snippet:

gui.popupTip("Hello, World!");
