This was a powerful feature I learned from the SAS Press book ODS the Basics by Lauren Haworth Lake which became the book ODS the Basics and Beyond https://www.sas.com/store/books/categories/examples/output-delivery-system-the-basics-and-beyond/prodBK_61686_en.html . This is great tool in the tool box. I tend to just use it for PROC FREQ output but know that it can work with most any PROC.
