Scrolling

Help!,
If I scroll the content of a view up to some position, and need to read from
the first displayed line on, how can I set the position of a reader at the
beginning of the first visible line on that scrolled view?.

Here is a fragment of my code:
 VAR v: TextViews.View; s: TextMappers.Scanner; org, dy, x: INTEGER;
...
 s.ConnectTo (v.ThisModel());
...
 v.SetOrigin (org, dy); (* scroll up v by -dy units *)
 s.SetPos (x); (** How to calculate this x?, the top line´s starting
character position *)
 s.Scan;
...
Best regards,
