What is the primary purpose of the SAS window or editor interface?

The primary purpose of the SAS window or editor interface is to submit program code interactively. This environment allows users to write, modify, and execute SAS code directly from the interface. When a user enters code into the editor, they can submit the code to the SAS program for execution, which enables immediate feedback and results. This workflow is essential for programming in SAS, as it facilitates an iterative process of coding, testing, and refining analyses.

The other options, while related to SAS functionality, do not capture the primary intent of the SAS editor. Viewing graphical outputs pertains to the results after code execution rather than the interactive submission of code. Managing library references is an important function but is not the central feature of the SAS window itself. Debugging errors automatically is a sophisticated feature that may assist users but does not define the core purpose of the editor interface, which focuses on code entry and submission.
