Many, many thanks everyone.
This thread has been really interesting to me, and apart from a couple of the early messages, totally flameless.
That is good.
I'm going to print it out, look up some references, and read some more.
One thing that I don't think has been covered, however, is where the differences in what constitute the '10 Commandments' originate.
My first post gives a link to 3 different versions, and I'm still unsure as to why that is so.
Explanations much apperciated.
Many thanks,
Paul
