Hello,
I was doing some exercises to prepare for my SAS's exam and most of the tasks were focuses on the dataset sashelp.class.
Therefore, as i was doing some data steps I forgot to create new datasets using sashelp.class and instead i overwrote it.
Is there any way to return to the initial stage of this dataset? Or can i download it somewhere and somehow replace it on my PC?
That's extremely important as i could not find any answer online.
Thanks,
Wojtek
