###Sorting

###Variant

var

###Loops

const
  JSN = '{ '+
        ' "adresses": [ '+
        '   { '+

      Memo1.Lines.Add('------');
    end;

Output adress = blabla city = Antalya pc = 7160

Or Enumerator

var
  X: ISuperObject;
  AMember,
  OMember: IMember;
begin
  X := TSuperObject.Create(JSN);

  for AMember in X.A['adresses'] do
  begin

          Memo1.Lines.Add(OMember.Name + ' = ' + OMember.ToString);

      Memo1.Lines.Add('------');
  end;

Output adress = blabla city = Adana pc = 1170
