E2450 There is no overloaded version of array property 'Item' that can
be used with these arguments

Delphi 2005 Ide
var
rd:AdsExtendedReader;

begin
rd:=FCommand.ExecuteExtendedReader;
rd['aa']:='aa';
end;


This works in 8.0 Provider and higer. I must use ADP 7.10.04. with ace
7.10 and database server 7.10.
