PRB: Resultset Column Must be a Formal Argument When Calling Oracle Procedure

SQL = "{call Oracle_Package.Oracle_Procedure ({resultset xx, column1, column2, column3})}"
set cmd = CreateObject ("ADODB.Command")
set rs = CreateObject ("ADODB.Recordset")
with cmd
   set .ActiveConnection = some_connection_object
   .CommandText = SQL
   .CommandType = adCmdText
end with
set rs = cmd.execute
				

CREATE OR REPLACE PACKAGE Oracle_package 
AS 
TYPE tcolumn1 is TABLE of  NUMBER(10) 
INDEX BY BINARY_INTEGER; 
TYPE tcolumn1 is TABLE of VARCHAR2(1000) 
INDEX BY BINARY_INTEGER; 
TYPE tcolumn3 is TABLE of VARCHAR2(2000) 
INDEX BY BINARY_INTEGER; 
PROCEDURE Oracle_Procedure
(column1  OUT  tcolumn1, 
column2   OUT  tcolumn2, 
column3   OUT  tcolumn3); 
END Oracle_package;
