Which of these windows displays previously executed results?

The Output and Results Viewer is the correct choice because it is specifically designed to display the results of previously executed SAS code. When you run a SAS program, the Output window presents the output data in a formatted way, while the Results Viewer provides an interactive interface to view the details of the analysis, graphs, and report outputs generated by the SAS procedures.

Using this window, users can easily navigate through results, and it allows for features like selecting results to copy, printing, or exporting them. This dual functionality streamlines the process of analyzing and auditing output data, making it an essential component for anyone working with SAS to review their results effectively.

In contrast, the Log window serves a different purpose by showing the results of the code execution path, including error messages, warnings, and information about the data steps and procedures. The Editor window is primarily used for writing and editing SAS code, without any focus on displaying executed results. Lastly, the Explorer window is more about managing SAS libraries, datasets, and files rather than showing outputs from code execution. Therefore, the Output and Results Viewer is the most appropriate choice for displaying previously executed results.
