Hi,
I am not sure about the Editor you are using - anyways, you can try this - put Mohan's code in a named Procedure and execute it :-
SQL> CREATE OR REPLACE PROCEDURE GET_COMBOS
  2  AS
  3   TYPE CHARTAB IS TABLE OF CHAR(1);
  4   CT1 CHARTAB:=CHARTAB('1', '2', '3');
  5   N1 NUMBER;
  6   N2 NUMBER;
  7   N3 NUMBER;
  8  BEGIN
  9   for n1 IN ct1.FIRST..ct1.LAST LOOP
10    for n2 IN ct1.FIRST..ct1.LAST LOOP
11     for n3 IN ct1.FIRST..ct1.LAST LOOP
12      dbms_output.put_line(ct1(n3)||ct1(n2)||ct1(n1));
13     END LOOP;
14    END LOOP;
15   END LOOP;
16  END GET_COMBOS;
17  /
Procedure created.
SQL> EXEC GET_COMBOS;
