Typical tasks include printing or performing statistical analysis, and may just require the user/programmer to identify the data set. This allows the user/programmer to concentrate on the details of working with the data within each record, in effect working almost entirely within an implicit program loop that runs for each record.Īll other tasks are accomplished by procedures that operate on the data set (SAS' terminology for "table") as a whole. The DATA step section of a SAS program, like other database-oriented fourth-generation programming languages such as SQL or Focus, assumes a default file structure, and automates the process of identifying files to the operating system, opening the input file, reading the next record, opening the output file, writing the next record, and closing the files. SAS Library Engines and Remote Library Services allow access to data stored in external data structures and on remote computer platforms. SAS components expose their functionalities via application programming interfaces, in the form of statements and procedures.Ī SAS program is composed of three major parts, the DATA step, procedure steps (effectively, everything that is not enclosed in a DATA step), and a macro language. Although non-programmer graphical user interfaces to SAS exist (such as the SAS Enterprise Guide), most of the time these GUIs are just a front-end to automate or facilitate generation of SAS programs. SAS is driven by SAS programs that define a sequence of operations to be performed on data stored as tables.
