Open cursor for and bind variables

Question

Hello all,
how can I assign values to a bind variable before opening a cursor?
example code:
DECLARE
   TYPE ref_cur_t IS REF CURSOR;
   l_ref_cur   ref_cur_t;
   l_query VARCHAR2 (100)
         := 'select * from table t1 where ndx= :var_index' ;
BEGIN
   -- assign a value to :var_index
   OPEN l_ref_cur FOR l_query;
END;Thanks!

Something like this ->
scott@ORCL>
scott@ORCL>DECLARE
  2     l_ref_cur   sys_refcursor;
  3     l_query VARCHAR2 (100) := 'select * from emp where empno = :var_index';
  4     l_empno  number(4);
  5  BEGIN
  6     l_empno := &emno;
  7     -- assign a value to :var_index
  8     OPEN l_ref_cur FOR l_query using l_empno;
  9  END;
10  /
Enter value for emno: 7698
old   6:    l_empno := &emno;
new   6:    l_empno := 7698;
