You can do it in PL/SQL but not in SQL. The following example demonstarte that -
satyaki>
satyaki>create or replace package S_glob
  2  as
  3       b varchar2(20);
  4  end;
  5  /
Package created.
satyaki>
satyaki>
satyaki>create or replace function S_test_mul_out(a in number,c out varchar2)
  2  return number
  3  is
  4     cursor c1(eno in number)
  5     is
  6        select ename,job,sal
  7        from emp
  8        where empno = eno;
  9      
10     rec c1%rowtype;
11     d  number(10);
12  begin
13       open c1(a);
14       loop
15         fetch c1 into rec;
16         exit when c1%notfound;
17          glob.b:= rec.ename;
18          c:= rec.job;
19          d:= rec.sal;
20       end loop;
21       close c1;
22       return d;
23  end;
24  /
Function created.
