Maximum execute immediate commands in a procedure

Question

Hi All,
I have written a procedure and my database size is 2 million records. i want to check for all special characters, as shown in my procedure. Is it possible to check for all special charachers like &39 to &255 checked within one single procedure. In that situation maximum immediate commands will be about 500.
I am sending my procedure just for one of the charachters.
CREATE or REPLACE PROCEDURE SPECIAL_YPOL1 (TABLENAME IN VARCHAR2,fieldname IN VARCHAR2)
AUTHID CURRENT_USER
IS
TYPE YPOLCurTyp IS REF CURSOR;
YPOL_cur      YPOLCurTyp;
sqlSt      LONG;
THEFIELD      VARCHAR2(250);
BEGIN
-- CHR(38)||39,
SQLST:= 'SELECT ' || UPPER(fieldname) ||' FROM '|| UPPER(TABLENAME) ;
          SQLST:=SQLST ||' WHERE ' || UPPER(fieldname) ||' LIKE ''%'' || CHR(38)|| ''39,%''';
               BEGIN
                    EXECUTE IMMEDIATE SQLST;
                    EXCEPTION WHEN OTHERS THEN
                    NULL;
               END;
     OPEN YPOL_CUR FOR SQLST;
     LOOP
          FETCH YPOL_CUR INTO THEFIELD;
               EXIT WHEN YPOL_cur%NOTFOUND OR YPOL_cur%NOTFOUND IS NULL;
                    SQLST:='UPDATE '||upper(UPPER(TABLENAME)) || ' SET '||UPPER(UPPER(fieldname)) ||' =REPLACE(' ||UPPER(fieldname)||','''||CHR(38) ||'39,'',CHR(39))';
                    SQLST:=SQLST||' WHERE '||UPPER(fieldname) ||' LIKE ''%'' ||CHR(38) || ''39,%''';
               BEGIN
                    EXECUTE IMMEDIATE SQLST;
                    EXCEPTION
                         WHEN OTHERS THEN
                         DBMS_OUTPUT.PUT_LINE('ERROR2');
               END;
     END LOOP;
COMMIT;
END SPECIAL_YPOL1;

You can use one more loop for that and catch all the special characters.
SQL> ;
  1  begin
  2      for i in 38..255 loop
  3         dbms_output.put_line(chr(i));
  4      end loop;
  5* end;
