Introduction to SAS Functions
Independent Consultant, Charlottesville, VA
A FUNCTION returns a value from a computation or system manipulation that requires zero or more arguments. And, like most programming languages, the SAS System provides an extensive library of "built-in" functions. SAS has more than 190 functions for a variety of programming tasks. This tutorial will cover the syntax for invoking functions, an overview of the functions available, examples of commonly used functions, selected character handling and numeric functions, and some tricks and applications of functions that will surprise you.
