That's very interesting - I didn't realize that it was sequential, but
it surely makes sense when I think about it. Thanks.

Following up on my original reply to the original question - I
attempted to transform the point from NAD83 to NAD27 with NADCON
(actually I used CORPSCON) and it refused to process the
transformation because it was outside the conus grid shift files,
which are the only datum shift files that I have.
