By: Harish Gulati

Overview of this book

SAS is one of the leading enterprise tools in the world today when it comes to data management and analysis. It enables the fast and easy processing of data and helps you gain valuable business insights for effective decision-making. This book will serve as a comprehensive guide that will prepare you for the SAS certification exam. After a quick overview of the SAS architecture and components, the book will take you through the different approaches to importing and reading data from different sources using SAS. You will then cover SAS Base and 4GL, understanding data management and analysis, along with exploring SAS functions for data manipulation and transformation. Next, you'll discover SQL procedures and get up to speed on creating and validating queries. In the concluding chapters, you'll learn all about data visualization, right from creating bar charts and sample geographic maps through to assigning patterns and formats. In addition to this, the book will focus on macro programming and its advanced aspects. By the end of this book, you will be well versed in SAS programming and have the skills you need to easily handle and manage your data-related problems in SAS.

Logic and control

We will look at three different sets of functions that will help us deal with logic and control issues.

IFC and IFN

There are also specific functions that return a value based on a condition that mirrors the IF and THEN capability we used earlier in the LAG example. The IFC and IFN functions are quite useful as they help the coding to be quite compact while delivering the required result. This helps reduce the processing time and debugging, if required. We will revisit the COALESCE function to showcase the IFN and IFC functions. The only difference between them is that the IFN function expects numeric arguments and resolves to a number, whereas the IFC function can take the first argument as numeric but expects...
