Learning SAS by Example, A Programmer's Guide, Second Edition, teaches SAS programming from very basic concepts to more advanced topics. Because most programmers prefer examples rather than reference-type syntax, this book uses short examples to explain each topic. The second edition has brought this classic book on SAS programming up to the latest SAS version, with new chapters that cover topics such as PROC SGPLOT and Perl regular expressions. This book belongs on the shelf (or e-book reader) of anyone who programs in SAS, from those with little programming experience who want to learn SAS to intermediate and even advanced SAS programmers who want to learn new techniques or identify new ways to accomplish existing tasks.In an instructive and conversational tone, author Ron Cody clearly explains each programming technique and then illustrates it with one or more real-life examples, followed by a detailed description of how the program works. The text is divided into four major sections: Getting Started, DATA Step Processing, Presenting and Summarizing Your Data, and Advanced Topics. Subjects addressed includeReading data from external sourcesLearning details of DATA step programmingSubsetting and combining SAS data setsUnderstanding SAS functions and working with arraysCreating reports with PROC REPORT and PROC TABULATEGetting started with the SAS macro languageLeveraging PROC SQLGenerating high-quality graphicsUsing advanced features of user-defined formats and informatsRestructuring SAS data setsWorking with multiple observations per subjectGetting started with Perl regular expressionsYou can test your knowledge and hone your skills by solving the problems at the end of each chapter.
