Example:

create procedure responder ()
language sql
result sets 1
begin
  declare mycur cursor with return to caller for
     select firstnme, lastname from employee order by lastname, firstnme;
  open mycur;
end!


create procedure caller (out firstname varchar(20), out lastname varchar(20))
language sql
begin
  declare loc result_set_locator varying;

  call responder();
  associate result set locator(loc) with procedure responder;
  allocate cur cursor for result set loc;
  open cur;
  fetch from cur into firstname, lastname;
  close cur;
