How to import, export Excel and SAS data

[#1]

In these two YouTube tutorials, SAS' @KathyKiraly addresses two popular questions asked here in the communities, around importing and exporting data. She reveals two ways to do each: through the LIBNAME statement and PROC IMPORT or PROC EXPORT.

This video helped. I was trying to figure out the difference between "libref", "libname", "data set" and "data step". Making the libname "X" was so simple, I was able to understand. 

It is hard to recognize what a data step is in the book when there are so many types of data steps, so I will have to just keep watching examples.

Until recently, I had the impression that I placed "libref" in the libname statement. Often the error message would come back as to paraphrase "libref doesn't exist", though it never told me what that meant. Now that I've got that misunderstanding behind me, I hope SAS won't be as confusing.  

Edit: I forgot to mention. I only watched half of the video, because I didn't want the new information in the video to confuse me, but as I go further in the SAS program, I'll get back to the rest.
