That does not realy answer my question. It was suggested to do something like this: procedure X(var Y); begin PInteger(Y)^ := 3; //syntax may be wrong, too lazy to test end; To me this completely defies the purpose of an untyped var parameter, since in this exmaple you do know, @design time, the type of Y, so why not write then procedure X(var Y: Integer); begin Y := 3; end; FillChar OTOH _is_ a good example of why you would use an untype var parameter.
