我曾写了个数据库转EXCEL的程序，在DELPHI5中没有任何问题。
但在但在DELPHI6，7中就有问题！代码如下：
ExcelApplication1.Connect;
ExcelApplication1.Workbooks.Add(null, 0);
ExcelWorkBook1.ConnectTo(ExcelApplication1.Workbooks[1]);
ExcelWorkSheet1.ConnectTo(ExcelWorkBook1.Sheets[1] as _WorkSheet);
在DELPHI6中编译时提示错误：undeclared identifier:'null'
怎么处理这句呢？
ExcelApplication1.Workbooks.Add(null, 0);
