Hi all
In practice, I saw some SAS codes like
libname macro "..\Macros\"; libname macro "..\..\Macros\";
and they always pointed to the correct destination.
So my question is, how does "..\" and '..\..\' work here? Is there any limitation to use dot dot?
This isn't a SAS specific topic, more of a computer file reference question.
I think this post explains the relative approach of using paths rather than absolute paths.

In Unix like environments
. represents current location or here
.. represents parent folder
These are relative representation of folder paths.
