The statement asserting that when using the default engine, you do not have to specify the engine name in the LIBNAME statement is accurate. In SAS, the LIBNAME statement is used to assign a library reference (libref) to a specific directory containing SAS data sets. By default, SAS uses the "BASE" engine, which means it can automatically determine how to read and write the data sets without requiring explicit specification of the engine.

This automatic handling streamlines the process of working with libraries by allowing you to simply provide the libref and the directory path. This means that when you're working with the default engine, it simplifies the syntax needed to define libraries, enabling users to focus more on their data and analyses rather than the specifics of the underlying engine.

While specifying the libref is still necessary to identify how you will reference the library throughout your SAS session, there is no need to explicitly identify the engine, as SAS assumes the default when it’s not specified.
