SAS/SQL (PROC SQL) allows you to connect those database and spreadsheet files through the ODBC (Open Database Connection). The IMPORT procedure can read these ASCII text files, but it can also import database (dBASE III, FoxPro, Access) and spreadsheet (Excel and Lotus 1-2-3) files. The INFILE statement also reads remote data files through the SAS/ACCESS using the TCP/IP, FTP, and URL protocols. SAS can read ASCII text files delimited with space, comma (CSV), tab, and other characters using the INPUT/INFILE/DATALINES statements in a DATA step. You may type in data and directly read them using the DATALINES (or CARDS) statement. SAS has a powerful feature of data manipulation that can handle various data sources such as ASCII text, database, and spreadsheet. A SAS data view is a virtual data set of descriptor information that points to data from other sources. A SAS data set is often referred to a SAS data file.
