excel - Refer to a workbooks by index number -

-

i using 

set newbook = workbooks.add

to create new workbook. need refer workbook without saving it. using workbook index number refer new workbook, there way retrieve index number of last workbook open/created (the highest index number)?

you can use last workbook

set lastworkbook = workbooks(workbooks.count)

but if have newbook variable, can't use that? reason because relying on workbook's index may not give consistent results.
