Thanks to Robert for this more explicit illustration of what Vilno
does. Its potential usefulness is clear.

I broadly agree with the comments that have been made about the
various approaches (with/without awk/sed/R etc).

Is there any URL that leads to a fuller explicit exposition of Vilno?

As I said previously, a web-search on "vilno" leads to very little
that is relevant. What I did find didn't amount to much.

Best wishes,
Ted.
