How to implement Forth?

Over the last years I played around with implementing a simple Forth interpreter. Now I am at it again. The best references I found for understanding the fundamentals were

• Leo Brodie’s Starting Forth,
• Dave Gauer’s Forth: The progamming language that writes itself: The Web Page,
• Brad Rodriguez’ Moving Forth, a series on writing Forth kernels,
• and especially the actual JONESFORTH implementation.
