REGION isn’t actually a statement but a comment. When you start a comment with region, SAS Studio recognizes it and treats the following lines – up to a comment marked /* endregion */ - as a collapsible block of code. This feature works in VS Code as well. It’s a practical way to group together data steps and procedures, allowing you to submit all the code in one go (Run Region) without having to manually select large sections. Regions can also be nested, as shown in the demo and example code. In SAS Studio, these regions are collapsible also in the SAS Log, making code management even easier. For a demonstration, see the video. You can find the code further down.
/* region main */
/* region connect to data */
