That's what I would normally do (e.g. for report generation)

But what I try to avoid is if I present a grid control to the user
which represents a really large dataset that he will scroll around
and fill up memory of the ws. It seem that IBO does many tricky
things e.g. with asc. and dec. keys. Isn't there a way to free
buffered records and us a descending key for scrolling back in the
grid ?

Sorry for so many questions but it is really much to investigate and
to learn before you could use such powerful tools in the right way.
