Abstract: IF-THEN/ELSE statements are simple and easy to use. However, IF-THEN/ELSE statements have their limitations. They are not always easy to read or to make changes to. They may also be less efficient than other methods that are available in SAS. Alternatives discussed include SELECT groups, ARRAY processing, and PROC FORMAT. The discussion includes examples about creating new variables out of existing ones, recoding variable values, validating data, and controlling output appearance.
