Final answer:
The statement that a LIBNAME statement can be used to create a permanent SAS library is true. A LIBNAME statement assigns a library reference to a collection of SAS datasets, and these libraries can be accessed in future SAS sessions as long as the path remains valid and the LIBNAME statement is re-executed or stored within an autoexec file.
Step-by-step explanation:
The question is about whether a LIBNAME statement can be used to create a permanent SAS library. The answer is true. A LIBNAME statement is indeed used in SAS (Statistical Analysis System) to assign a library reference to a collection of data sets or files. This allows users to reference and access datasets within these libraries efficiently throughout their SAS session.
To create a permanent SAS library, you would specify a libref (a shorthand reference name) and a path to a folder location on your operating system where the SAS datasets will be stored. Here is a basic example of how a LIBNAME statement may look:
LIBNAME mylib 'C:\path\to\my\permanent\folder';
In this example, 'mylib' is the libref that will be used to refer to the library in the SAS program, and 'C:\path\to\my\permanent\folder' is the path to where the library is stored on the local machine. Once you have executed this statement, you can use 'mylib' in your SAS code to reference this permanent library.
It is important to note that the library will persist beyond the current SAS session and will be available for future SAS sessions as long as the LIBNAME statement is executed or the path and libref remain valid.
The libref is considered permanent in the sense that the data within the specified location can be accessed in future sessions; however, the libref itself will expire at the end of the SAS session unless it is saved within a SAS autoexec file or redefined in a subsequent session.
