Which component allows navigation through libraries and data sets in SAS?

The component that allows navigation through libraries and data sets in SAS is the Explorer. The Explorer window provides a user-friendly interface for users to browse and manage their SAS libraries, data sets, and other resources. Through this component, users can easily view the contents of different libraries, open data sets, and perform various tasks such as importing or exporting data.

The Explorer is particularly useful for those who may not be familiar with using SAS programming language commands to manipulate data, as it offers a visual representation of the available data. This enhances productivity by allowing users to quickly find and access the data they need.

In contrast, the Log provides information about the execution of the SAS program, including error messages and processing details. The Results window displays output generated from procedures and analyses, while the Editor is used for writing and editing SAS code. While these components are essential for different aspects of programming within SAS, they do not specifically facilitate the navigation of libraries and data sets like the Explorer does.
