About the webinar
Arrays in the SAS DATA step have been around for many years, yet they remain highly relevant and powerful. In this session, you will see how arrays can simplify code and solve common programming challenges efficiently.
We will walk through practical examples of both one-dimensional and two-dimensional arrays, demonstrating when and how to use them. We will also explore alternative approaches so that you can choose the best method for your use case. All code examples will be shared after the webinar for you to download and use in your own environment.
What you'll learn
- Create numeric and character one-dimensional arrays and loop through their elements.
- Use arrays to transpose data (convert rows to columns and vice versa) in the DATA step.
- Create two-dimensional arrays and load values from datasets into them.
- Identify when arrays are the best approach, and when alternatives such as Hash objects may be more suitable.
