Reading columns after a "fetch_rows" command

Question

Dear All:
Could somebody help me with this issue?
The following is a sample code to declare, open and fetch a Dynamic Cursor using BIND_ARRAY command ...
declare
c number;
d number;
n_tab dbms_sql.Number_Table;
indx number := -10;
begin
c := dbms_sql.open_cursor;
dbms_sql.parse(c, 'select cod from emp order by 1', dbms_sql);
dbms_sql.define_array(c, 1, n_tab, 10, indx);
d := dbms_sql.execute(c);
loop
d := dbms_sql.fetch_rows(c);
/* The problem is here ...... */
/* After to read the first row, I can not identify a way to read the following row fetched, how can I read the first 10 rows fetched and stored in n_tab variable? */
dbms_sql.column_value(c, 1, n_tab);
exit when d != 10;
end loop;
dbms_sql.close_cursor(c);
exception when others then
if dbms_sql.is_open(c) then
dbms_sql.close_cursor(c);
end if;
raise;
end;
The problem is that I can not identify a way to read each row fetched in n_tab after the fetch_rows command, It's supposed that n_tab store 10 rows each time, but how can I read these 10 rows? Is it enough with the column_value command? after this Do I have to reference each row by n_tab[1], n_tab[2] .... n_tab[10] to read the codes fetched?
Thank you to everybody for your attention
Regards
Josi
