WHAT is SAS? SAS stands for STATISTICAL ANALYSIS SYSTEM. 
  The SAS System is an integrated suite of software for enterprise-wide information 
  delivery. The functionality of the system is built around the four data-driven tasks 
  common to virtually any application -- data access, data management, data analysis and 
  data presentation. Applications of the SAS System include executive information systems;
  data entry, retrieval, and management; report writing and graphics; statistical and 
  mathematical analysis; business planning, forecasting, and decision support; operations 
  research and project management; statistical quality improvement; computer performance 
  evaluation; and applications development. The SAS System is modularly designed to give 
  organizations the flexibility to license only the functionality they need. As their 
  needs grow and change, additional components can be added on in a completely integrated 
  manner across the wide range of computing environments supported by the software.

3. DATA MODEL

4. read data (data reading, infile)
Using the RECFM= option in the FILENAME, FILE, %INCLUDE, and INFILE statements enables 
you to specify the record format of your external files. The following example shows you 
how to use this option.
Usually, the SAS System reads a line of data until a carriage return and line feed 
combination ('0D0A'x) are encountered or until just a line feed ('0A'x) is encountered. 
However, sometimes data do not contain these carriage control characters but do have 
fixed-length records.  In this case, you can specify RECFM=F to read your data.

To read such a file, you need to use the LRECL= option to specify the record length and 
the RECFM= option to tell the SAS System that the records have fixed-length record 
format.  Here are the required statements:

data test;
  infile "test.dat" lrecl=60 recfm=f;
  input x y z;
run;

In this example, the SAS System expects fixed-length records that are 60 bytes long, and 
it reads in the three numeric variables X, Y, and Z.
You can also specify RECFM=F when your data do contain carriage returns and line feeds, 
but you want to read these values as part of your data instead of treating them as 
carriage control characters.  When you specify RECFM=F, the SAS System ignores any 
carriage controls and line feeds and simply reads the record length you specify.
