What Is SAS Code?

SAS (Statistical Analysis System) is a powerful software suite that allows users to perform advanced data analytics, generate reports, and make data-driven decisions. SAS code refers to the programming language used in SAS software to manipulate and analyze data.

Getting Started with SAS Code

If you are new to SAS code, don’t worry! It may seem intimidating at first, but once you understand the basics, you’ll be able to harness the full potential of this versatile tool.

To write SAS code, you need a basic understanding of programming concepts. You don’t have to be an expert programmer; however, knowing the fundamentals will make your journey with SAS smoother.

SAS Code Structure

SAS code is written in statements and each statement ends with a semicolon (;). These statements are executed sequentially by SAS. Here’s a simple example:

data mydata;
  input name $ age;
John 25
Jane 30

In this example, we define a dataset named “mydata” using the data statement. The input statement specifies the variables within the dataset – “name” and “age”. The actual data is provided using the datalines statement.

Data Manipulation with SAS Code

SAS code allows you to manipulate data in various ways. You can filter observations based on certain criteria, create new variables, merge datasets, and perform calculations. Here’s an example:

data filtered_data;
  set mydata;
  where age > 25;

In this code snippet, we create a new dataset named “filtered_data” using the data statement. The set statement specifies the source dataset, and the where statement filters the observations where age is greater than 25.

SAS Code Output

SAS code produces outputs in various formats, such as tables, graphs, and reports. The output can be viewed within SAS itself or exported to different file formats like Excel or PDF.

To generate a basic table output from your SAS code, you can use the proc print procedure:

proc print;
  title 'My Data Output';
  var name age;

The proc print procedure prints the selected variables (name and age) from the dataset. The title ‘My Data Output’;‘ statement adds a title to the output table.

SAS Code Documentation and Commenting

To ensure your code is easily understandable and maintainable, it’s essential to document it properly. You can add comments in SAS code using an asterisk (*) or by wrapping them between /* and */.

* This is a comment in SAS code;

spanning multiple lines.


SAS code is a powerful tool for data manipulation and analysis. Understanding the basics of SAS code structure, data manipulation techniques, output generation, and proper documentation will help you become proficient in using this software suite. So, go ahead and start exploring the world of SAS code!
