In Zope you have "DTML Methods" and "DTML Documents". Both are

 Ah. Sorry. Many years with development of other systems left me using the
wrong grammar. The 'page' would be what I'd hoped to display in a browser

 Ok, so, after starting with the book, one of the first things it says is..

 So, I tried to go to that page, and I got the following in my logs...

 I've a feeling it's the same misconfiguration that happened when I tried to
go ahead and create an index_html object, which was what I thought I had
done when I'd played with Zope 2.3 or whatever, a few years back.
