What does the PROC CONTENTS procedure produce as output for the DATA work.look?

The PROC CONTENTS procedure provides information about the structure of a SAS data set, specifically generating the descriptor portion of that data set. This descriptor information includes details such as the names of the variables, their types, lengths, labels, formats, and other metadata. When applied to the data set work.look, PROC CONTENTS will generate an output that outlines this metadata, allowing users to understand the organization and attributes of the data without displaying the actual data values or observations contained in the data set.

In contrast to other options, PROC CONTENTS does not show the code that created the data set, nor does it display any observations or the actual data values within the data set. It focuses solely on the metadata aspect, making it an essential tool for quickly assessing the characteristics of a data set in SAS.
