I think it is mainly used for TIB_Queries (I don't know about the TIBO
components) attached to a TIB_Grid. In the TIB_Grid you can select one
or more rows, and the number of selected rows I expect to find in
RowsSelected.

What you prepare is the query statement, explaining how Firebird will
go about fetching the result set. Judging from the time it takes to
return rows, it is only sometimes (when it doesn't sort and doesn't
use indexes for the sorting) that it has to know the entire result set
before starting to return rows.
