SAS System 9.0

SAS System Viewer is a software application developed by SAS Institute Inc. that allows users to view SAS datasets, catalogs, and projects without having to run the SAS software itself. The program provides an easy-to-use interface that enables users to navigate through SAS datasets and explore their contents.

The viewer's main screen displays a list of available SAS datasets, which can be sorted by name, type, or date modified. Clicking on a dataset displays its variables and associated properties, such as format, length, and label. Users can view the data within a variable, as well as sort or filter the data according to specific criteria.

The SAS System Viewer also allows users to view SAS catalogs and projects. Catalogs are collections of SAS files that can be used to organize and share SAS content, while projects provide a way to manage multiple SAS programs and data sets in a single location.

In addition to its viewing capabilities, the SAS System Viewer also provides basic data analysis features. Users can generate frequency distributions for variables in a dataset or generate summary statistics such as mean, median, and standard deviation. These features make it easier for users to get a quick overview of their data without having to write code in SAS.

The SAS System Viewer is a useful tool for anyone who needs to view or analyze SAS datasets but doesn't want to use the full SAS software package. Its intuitive user interface and basic analysis tools make it easy for users of all skill levels to work with SAS data.
