I have another one for the group, but I will save it for another day ;)
I have been looking for contact details for the author to ask him what he was eluding to with the exercise, but to no avail.

This lights my frustration fire. I wonder whether the author tested the
book?
When I worked for a training company I was asked to test a new on-line
course on JCL. I demurred by saying "But I don't know JCL.". The reply
was "that's exactly what we want!"
So a general recommendation to authors is to have a member of the target
audience "test" the book. You Jon have done that but at some cost to you
and those of us on this list.
