oracle error line number into stored procedures

hello,

I've a package with a lot of stored procedures in it and I've to execute it on Oracle Client 11... to not insert messages after any line of code to intercept the errors ... exists there any oracle error msg that indicates the line (on the st.prcd)  or the name of the st.Procedure where the error succeded in case of Exception (appart from SQLCODE and SQLERRM from )?

------------------------------------------

st. prcd ...

.....

.....

....

exception
    when others then
      Rollback;
      paMinorCode:=SQLCODE;
      paMinorMsg:=SQLERRM;
      return;

end;

-------------------------------------------

thank you
