If you search Google for "computer programming tutorial", "learn ns basic", "learn haxe", "learn rebol", "learn rfo basic", and other topics, you'll see my instructional texts at the top of every first page in the search results. I've been programming for more than 30 years, and have been an entrepreneur/business owner for more than a quarter of a century. I've written software and designed computing systems which help run hundreds of businesses and organizations, from small mom and pop start-ups to major corporations. The web site in my profile is an 800 page book about business programming with Rebol (my favorite development tool).
