Learning SAS: A Guide to String Concatenation with CAT, CATS, and CATX Functions

String manipulation is a fundamental requirement in almost every data processing workflow. In SAS, the process of combining two or more character variables into a single variable is known as string concatenation. While traditional methods like the double pipe operator (`||`) exist, SAS provides a powerful family of functions—the CAT functions—that are specifically designed to
