Checking for correctness: We can check if there are errors in the data.Modifying the data: We can modify the existing data and create new data sets and update the existing the data.Creating the Data: We can input the data or read from the files, subsets of the existing data, merging the more than one data set, or updating the data.Defining the structure of the data: We can define the variables and assign the data.DATA step(s):ĭata Steps used to Create or modify the data sets. SAS programs are composed of two fundamental components, Data Step and Proc Step (Procedures). Also, menu driven interface for SAS is not provided for platforms like UNIX and Mainframe. SAS programs provide high level of flexibility compares to the menu driven interface. However, most of the interaction with SAS system to perform analytical operations are done through writing SAS programs. SAS also provides menu driven graphical user interfaces (such as the SAS Enterprise Guide (EG), SAS Enterprise Miner (Eminer)) which helps non-programmer.

SAS is driven by SAS programs or procedures, which we can use to perform various operations on data stored as tables called Datasets. Introduction to SAS – What is SAS program?
