Which statement about LIBNAME statements is false?

They can be stored with a SAS program to reference the library automatically.
When deleted, files in the library are no longer accessible.
Librefs can last from one SAS session to another.
You can access files created with other vendors' software by submitting a LIBNAME statement.

The correct answer is: Librefs can last from one SAS session to another.

The correct answer highlights a misconception about the nature of librefs in SAS. Typically, librefs, or library references, are temporary and exist only during the active SAS session in which they are created. Once the session ends, the libref is lost, and you cannot access the referenced library in a new session without redefining it. When a LIBNAME statement is issued, it establishes a connection between SAS and the specified library for only the duration of the current session. Therefore, for subsequent SAS sessions, users need to reissue the LIBNAME statement to access the same library again, which makes the statement about librefs lasting from one session to another inaccurate. In contrast, the other statements hold true: LIBNAME statements can indeed be saved alongside SAS programs for future reference, deleting files from a library makes them inaccessible, and you can use LIBNAME statements to work with files from various software vendors, provided that the appropriate engine is specified in the statement.
