Which method allows you to directly see your data while using SAS?

The DATALINES statement is a method in SAS that enables users to input data directly into the data step while simultaneously allowing visibility of that data as it is being defined. When utilizing DATALINES, data can be entered inline with the DATA step code, making it easy to view and edit the data structure alongside the corresponding variables and observations.

This method provides immediate feedback since the data is included directly within the program flow, making it simpler to manage small datasets without needing an external file or complex input commands. DATALINES also allows for a clear and straightforward approach for beginners or during the initial stages of data exploration and manipulation.

In contrast, using INFILE pertains to reading data from external files, which can complicate the immediate visibility of data, especially if large files are involved. The INPUT statement is used within the context of reading data that has been brought into the program, which may limit direct visibility without first properly setting up the data. Lastly, the DATA step itself is a broader construct for data processing but does not specifically denote a method for visualizing data without additional statements like DATALINES.
