Well, just for the record, I based my "reductionist" answer on the
following clue from Astrid Kuhr's original post:

I took this to mean that Kuhr may not have been familiar with the

Perhaps I assumed incorrectly that Kuhr may have been using the Z device
simply to avoid using the screen (as in a batch process, for example).

anyone when I post replies if I am going to post something that may
be taken as some kind of criticism.
