Question on Getting Path in SAS

angelinading — Fri, 05 Jun 2020 18:40:53 GMT

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.
