In reply to Samuel Vargas.

I am sorry that the book is not meeting your expectations. The book's title is Simulating Data with SAS, and the purpose of the book is to show how to GENERATE random data from distributions and from statistical models (such as regression models). Thus most programs do not use INPUT and DATALINES statements to read observed data. Instead, they use the RAND function and the OUTPUT statement to generate data sets with desirable statistical properties.

I suggest that you post a specific question to the SAS Support Community. Many experts, including myself, participate in the community and can help you understand how to solve your work-related problems by using SAS.
