Return package cursor from another store procedure

Question

Hello
I’m new in Oracle, and I have the following problem:
I have an cursor in a package defined like that:
create or replace
PACKAGE "TestPACKAGE" AS
cursor DOWNLOAD_CURSOR is select A.* from Table1 A, Table2 B
END TestPACKAGE;
In reality there is more than one package with different cursors. I want to use that DOWNLOAD_CURSOR in a store procedure, function or another package, to return it to the client as a ref cursor.
Something likes that:
create or replace
procedure aa_test (retCURSOR OUT sys_refcursor) is
begin
retCURSOR := TestPACKAGE.DOWNLOAD_CURSOR;
end;
or to replace that procedure with another method to return data, and use them in a .NET application.
