A simple Forth program that prints a message to the screen from the interpreter.

The word ." scans ahead in the input buffer for a matching " and displays the intervening string. The initial space is ignored, since it is required to separate the word from the text to display.

The word CR (for Carriage Return) prints a newline.

<<hello_world.fs>>=
." Hello World!" CR
