Hi, In the official SAS specialist prep guide, page 46 on reading a SAS data set to create another data set, here is the screenshot.
I do understand the purpose of line 2 is to create a library where I can store the MALES dataset. However, there is no file or folder called "Men50" in the 'C:\Users\Student1\cert\' directory. The book does NOT tell us to create a folder called "Men50" before you use LIBNAME statement to reference it.
So when I ran the code, I got an error even though I can see that MEN50 library was successfully created by SAS. So my question is, we always need to create the folder or make sure it exist in the physical file path before using LIBNAME to create a library for it?
