Thanks, Roger, I was about to make the point that this paper has never been published in Vector, and is not in Edn1 of the book APWJ.
It was an open question at one stage as to whether it should be included in Edn2, bringing the number of papers up to 42 (appealing, if you're a Hitchhikers fan). But I fear it will not sit well there, cerainly not as the first paper in a book aimed at J novices.
