PharmaSUG 2014 - Paper BB08 Express yourself ! Regular Expressions vs SAS Text String Functions Spencer Childress, Rho , Inc., Chapel Hill, NC ABSTRACT SAS and Perl Regular expression functions offer a powerful alternative and complement to typical SAS text String functions. By harnessing the power of Regular Expressions , SAS functions such as PRXMATCH and PRXCHANGE not only overlap functionality with functions such as INDEX and TRANWRD, they also eclipse them. With the addition of the modifier argument to such functions as COMPRESS, SCAN, and FINDC, some of the Regular expression syntax already exists for programmers familiar with SAS and later versions. We look at different methods that solve the same problem, with detailed explanations of how each method works. Problems range from simple searches to complex search and replaces. Programmers should expect an improved grasp of the Regular expression and how it can complement their portfolio of code.
