*.log − It represents the SAS Log File it contains information such as errors, warnings, and data set details for a submitted SAS program. *.sas − It represents the SAS code file which can be edited using the SAS Editor or any text editor. The SAS programs, data files and the results of the programs are saved with various extensions in windows. If the SAS data set name is omitted then SAS creates a temporary data set with a name generated by SAS like - DATA1, DATA2 etc. Which means the data set persists after the session is over. The data set name can be prefixed with a library name which makes it a permanent data set. Which means the data set gets erased at the end of the session.

The rules for DATA set creation are as below.Ī single word after the DATA statement indicates a temporary data set name. The DATA statement marks the creation of a new SAS data set. RainfFall% # contains apecial character other than underscore. It must start with the letters A through Z (not case sensitive) or an underscore (_).Ĭan include numbers but not as the first character. The variable names follow the below rules. Variables in SAS represent a column in the SAS data set. Space can be used to separate the components in a SAS program statement.Įvery SAS program must end with a RUN statement. Many SAS statements can be on the same line, with each statement ending with a semicolon. A semicolon at the end of the last line marks the end of the statement. Statements can start anywhere and end anywhere. The three components of any SAS program - Statements, Variables and Data sets follow the below rules on Syntax. Like any other programming language, the SAS language has its own rules of syntax to create the SAS programs.
