Dynamic query results parsing/ dynamic reports

Question

Is there a way of creating a cursor at runtime, then querying the contents of the the fields of the cursor, without knowing the names and field type of the individual columns at design time?
Say I did as a basic example
Create table testtable( id number,name varchar2(200), address1 varchar2(200),address2 varchar2(200),address3 varchar2(200),dateopened date);
Create or replace procedure testproc(v_query in varchar2(2000)) is
type cur_typ is REF CURSOR;
c_cursor cur_type;
BEGIN
open c_cursor for v_query;
loop
fetch the row into some sort of dynamic record dynrec;
exit when _cursor%notfound;
something like
if dynrec.fields(3).field_type='Date' then
dbms_output.putline( to_char(fields(3),'dd/mm/yy'));
else
dbms_output.putline(fields(3));
end if;
end loop;
close c_cursor;
END;
then i'd be calling it with
testproc('select name, address1,dateopened from testtable where id=24');
or
testproc('select address1,address2,address3 from testtable where id=24');
how do I define the dynamic record without knowing what table it refers to? And, how do I get the column contents?
Thanks for your input

You'll need a combination of USER|DBA|ALL_TAB_COLUMNS and the DBMS_SQL package.
Sorry, don't have time for more of a hint than that.
