I am starting a new job and want to write code that looks professional and is easy for others to maintain. Are there standard style guides for SAS? For example, how should I indent my data steps or use comments? I want to avoid bad habits early on.
SAS programming standards prioritize consistent indentation of data steps, explicit variable naming, and the use of comment blocks to ensure code maintainability.

There isn't one universal SAS style manual, but the most widely accepted standard is the SAS Institute's own white paper on coding standards. Keeping your code clean is about readability for the next guy, so use consistent indentation for every step and document your logic blocks before you start writing them.
I remember when I inherited a legacy codebase that looked like a bowl of spaghetti code with no indentation or meaningful headers. It took me three weeks just to untangle the macro logic because someone thought that writing everything in a single massive block was clever.
Ever since that nightmare, I treat every script like a public document. I spent months training my team to use white space effectively and comment every complex conditional statement so that the next person doesn't have to rebuild the logic from scratch.
You should adopt a standardized syntax structure to ensure your production code remains readable and debuggable.
- Always use four-space indentation for every inner data step block.
- Place labels above every procedure to track input datasets.
- Include a standard header block at the top of every file.
- Use consistent lower case for keywords to reduce visual noise.
- Separate long macro calls into distinct lines for clarity.
