It suggests coding techniques, provides guidelines for their use, and compares examples of acceptable and improved ways to accomplish the same task. Most of the tips are limited to DATA step applications. Efficiency For the purpose of this discussion, efficiency will be defined simply as obtaining more results from fewer computer resources.
