To use SAS it is
necessary that you are acquainted with the scripting known as SAS
language. SAS programs are written using SAS language to manipulate,
clean, describe and to do data analysis.
A SAS program consists of a
series of DATA, data transformation and PROCedure statements. An entry
level SAS user should at least know how to use the following SAS
statements to have a good start with the language.
IF / THEN; ELSE;
In the chapters that
follow, you get more familiar with these statements/procedures and
various features and options that are available with each one of them.
Examples and code samples are also provided to get a better
understanding of these statements and procedures.
Please note that the methods described in these pages to learn

are written to train the beginners in a comprehensive and systematic
way. This method is developed by the author based on his
own limited experience with SAS so readers
please use their own judgment.
