procedure do_insert_rec()
is
begin

declare cursor a is select * from .........   arec a%rowtype;
  begin
    open cursor a;
    loop
    fetch cursor a into arec; exit when a%nofound;

       
       do_proc_a; <-- this procedure inserts a record, but record is 
                      not committed.
       stmts;

       declare cursor b is select * from .........
         brec b%rowtype;
         begin
           open cursor b;
           loop
           fetch cursor b into brec; exit when b%nofound;
       
              do_proc_b; <-- with in this procedure call, if a 
                             rollback stmt is is issued, i get the 
                             ora-01002 error when it goes to fetch 
                             the next record. This never happened

              stmts;

           end loop;
           close b;
         end;

    end loop;
    close a;
