Open SYS_REFCURSOR for DYNAMIC SQL

Question

Hi!
I have stored procedure like below:
CREATE OR REPLACE
PROCEDURE MYPROCEDURE
cv_r OUT SYS_REFCURSOR
AS
lv_ExecuteString varchar(2000);
BEGIN
  lv_ExecuteString := 'select 1 from dual';
  open cv_r for lv_ExecuteString;
  END MYPROCEDURE;and then
SQL> var y refcursor
SQL> execute myprocedure(:y);
BEGIN myprocedure(:y); END;
ERROR at line 1:
ORA-00911: invalid character
ORA-06512: at "BPATEL.MYPROCEDURE", line 9
ORA-06512: at line 1shouldnt it suppose to work??? If not then How can I fill up OUT SYS_REFCURSOR with dynamic sql string ???
although If I modify this below in my stored procedure it works fine:
-- open cv_r for lv_ExecuteString;
open cv_r for select 1 from dual;
SQL> var y refcursor
SQL> execute myprocedure(:y);
PL/SQL procedure successfully completed.
SQL> print y
         1
         1any idea?? why is it doing so???
