Is there any chance that I can persuade you to follow Usenet conventions
and (1) snip signatures; (2) reply in-line to the points being made?

The code you posted does not permit any base.

The discussion would be more productive if you addressed the points made
rather than quoting the full message and the adding something that you
feel is relevant at the end.  I explain exactly why your code does not
permit any base and exactly why I though that was a key part of your
project.  You did not address either of these points.
