SQL Format Question (sorry about the previous post)

Question

I'm trying to create a query that will produce the following output:
DNAME ENAME
ACCOUNTING CLARK, KING, MILLER
RESEARCH SMITH, ADAMS, FORD, SCOTT, JONES
SALES ALLEN, BLAKE, MARTIN, JAMES, TURNER, WARD
As opposed to this basic query:
SQL> get test.sql
1 break on dname
2 select dname, ename
3 from dept, emp
4 where emp.deptno=dept.deptno
5* order by dname
SQL> start test.sql
DNAME ENAME
ACCOUNTING CLARK
KING
MILLER
RESEARCH SMITH
ADAMS
FORD
SCOTT
JONES
SALES ALLEN
BLAKE
MARTIN
JAMES
TURNER
WARD
Any suggestions on how to accomplish this?
Thanks in advance!

-- Here is one way to do it in Oracle 8i:
-- First, run the script below to create
-- a concatenation funciton:
CREATE OR REPLACE FUNCTION concatenate
  (p_col1  IN VARCHAR2,
   p_table IN VARCHAR2,
   p_col2  IN VARCHAR2 DEFAULT '1',
   p_value IN VARCHAR2 DEFAULT 1,
   p_delim IN VARCHAR2 DEFAULT ', ')
  RETURN VARCHAR2
IS
  TYPE cursor_type IS REF CURSOR;
  c1          cursor_type;
  v_sql       VARCHAR2 (4000) := NULL;
  v_temp      VARCHAR2 (1000) := NULL;
  v_concat    VARCHAR2 (1000) := NULL;
  v_delim     VARCHAR2 (3)    := NULL;
BEGIN
  v_sql :=
     ' SELECT '   || p_col1
  || ' FROM '     || p_table
  || ' WHERE '    || p_col2  || ' = '''
                  || p_value || ''''
  || ' ORDER BY ' || p_col1;
  OPEN c1 FOR v_sql;
  LOOP
    FETCH c1 INTO v_temp;
    EXIT WHEN c1%NOTFOUND;
    v_concat := v_concat
             || v_delim
             || v_temp;
    v_delim := p_delim;
  END LOOP;
  CLOSE c1;
  RETURN v_concat;
END concatenate;
--Then to use the function in a query:
COLUMN   enames FORMAT A50 word_wrapped
SELECT   DISTINCT dname,
         concatenate ('ename', 'emp',
                      'emp.deptno', emp.deptno) enames
FROM     dept, emp
WHERE    emp.deptno = dept.deptno
ORDER BY dname, enames
-- results:
DNAME          ENAMES
ACCOUNTING     CLARK, KING, MILLER
RESEARCH       ADAMS, FORD, JONES, SCOTT, SMITH
SALES          ALLEN, BLAKE, JAMES, MARTIN, TURNER, WARD
