* require 'win32ole'
*
* excel = WIN32OLE.new('Excel.Application')
* excel.visible = true
* workbook = excel.Workbooks.Add();
* worksheet = workbook.Worksheets(1);

* worksheet.Range("D2").value = 20;
*
* range = worksheet.Range("A1:D2");
* range.select
* chart = workbook.Charts.Add;
*
* workbook.saved = true;
*
* excel.ActiveWorkbook.Close(0);
* excel.Quit();
*
* Unfortunately, Win32OLE doesn't support the argument passed by
* reference directly.
* Instead, Win32OLE provides WIN32OLE::ARGV or WIN32OLE_VARIANT object.
* If you want to get the result value of argument passed by reference,
* you can use WIN32OLE::ARGV or WIN32OLE_VARIANT.
*
* oleobj.method(arg1, arg2, refargv3)
* puts WIN32OLE::ARGV[2] # the value of refargv3 after called oleobj.method

* WIN32OLE::VARIANT::VT_BYREF|WIN32OLE::VARIANT::VT_XXX)
