How To Get Line And Error Code From EXECUTE IMMEDIATE P_SQL

I'm trying to write my own application ( in Delphi) which should be work similar to the Oracle SQL Developer. I received the body of the selected stored procedure by select * from all_users where type='PROCEDURE' and NAME='name_of_the_selected_proc'

Next, I put the body of the procedure into richedit component, make necessary changes, then put the corrected body into the variable ( varchar2) which is the input parameter of my stored procedure PW_DO_IT

create or replace PROCEDURE PW_DO_IT(P_SQL in varchar2)
as
begin
EXECUTE IMMEDIATE P_SQL;
end;

Everything works fine , the only problem is that I don't know how to get the line in which simulated error occured and its details. The only thing I get is the ORA-24344: success with compilation error
