NOTE: Libref U was successfully assigned as follows: This produces a log which, in it's own way, says that the file was successfully saved. The basic code to save a SAS data set using the SAS name is libname U "U:\" In the SAS example above, u is a library name while class is the data file name. In SAS file names, the location is given by a prefix called a library name. In operating systems names, the file path (location) is included as part of the file name specification. Operating system file names are ALWAYS enclosed in quotes, while SAS file names are NEVER in quotes. On either operating system the SAS name for these data files might look like u.class While a Linux data file name could look like "~/SAS64/class.sas7bdat" For example a Windows data file name might look like "U:\SAS64\class.sas7bdat" The operating system file name might include the location (the directory or folder) as well as the file name. SAS names a usually preferred, because they make your code more portable and easier to read, write, and maintain. In your SAS code, these data files can be addressed in either of two ways, either using an operating system name or using a SAS name. Ordinary SAS data sets are kept as files in your computer's file system, rather than being loaded in your computer's memory. These are usually saved by writing some SAS code, as opposed to clicking on a "Save" icon on the Toolbar or in the menus. But it can span multiple lines and can be of any length.In order to process any data, that data must be in the format of a SAS data set, a special SAS binary file which usually has the file extension ".sas7bdat". Following is a single line comment example −įollowing is a multiline comment example −Ī comment in the form of /*message*/ is used more frequently and it can not be nested. It can span multiple lines and can be of any length. Also there should not be any reference to any macro statements inside such comments. *message type commentĪ comment in the form of *message can not contain semicolons or unmatched quotation mark inside it. *.sas7bdat −It represents SAS Data File which contains a SAS data set including variable names, labels, and the results of calculations.Ĭomments in SAS code are specified in two ways. *.mht / *.html −It represents the SAS Results file. *.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.
