In this case "macros.tmp" is a text file that the data _null_ step writes results as SAS reads from the URL. The code for that step is basically writing selected lines from the website.
It is generally a good idea to use a fully qualified path and name for such files as you may not always have permissions to write to the relative position that this file would be written, such as when the cod executes on a server or similar environment.
If you don't have a good internet connection, there is a permissions issue or some network setting that doesn't allow you to have access to support.sas.com at the moment you would get that error.
Instead of using code that seems not to run you could go to the web page and see this text:

Copy and save that as a program file. Then run it to make the macro templates available.
