Class 3 SAS Data Libraries

When libref is missing, the table is created in the work library

At the end of the SAS session, the contents of your work library are deleted. This means that any temporary datasets or files that were created during the session will be removed from the work library. It is important to save any important data or results to a permanent location before ending the session to avoid losing any valuable information.

The Data step A does not create a permanent data set. The creation of a permanent data set requires the use of PROC or DATA steps with appropriate options to specify the permanent location and format of the data set. In this case, since the question does not mention any PROC or DATA step options related to creating a permanent data set, it can be concluded that the statement is false.

In a Windows environment, a library is analogous to a folder. A folder is a container that holds files and other folders, allowing for organization and easy access to the stored information. Similarly, a library in Windows serves as a container for related files and resources, providing a centralized location for managing and accessing them. Just like a folder, a library can be used to group and categorize files based on their content or purpose, making it easier to locate and work with the desired files.

All libref should begin with a letter or underscore and must be 8 characters or less. No special characters except _ is allowed.
