too much work there's a simpler way to do it without multiple cursors.
Use a scroll cursor and fetch relative.
Fetch relative allows you to fetch a record set relative to your current
position.
If you are on 11, you fetch negative 10 and your back to one.
If you need a sample let me know.

I don't see that working with key positioning. As you can see in the
example, I am positioning to a given invoice number. As far as SQL is
concerned that there is no invoice less than the value entered so you
cannot do a fetch relative backwards because nothing exists before the
invoice I positioned to.
If I am missing something, yes, I would appreciate some samples.
