![]() ![]() INFILE should be used in a DATA step, while PROC IMPORT and PROC EXPORT are independent procedures. You may use the PUT statement in a Data Step or PROC EXPORT to export data sets into external files. In general, SAS reads data using the INFILE statement and PROC IMPORT. In SAS, there are various data sources as shown in the following figure. Otherwise, you have to add " noterminal" to a command (e.g., " sas -noterminal file_name.sas"). In UNIX, PROC IMPORT and PROC EXPORT must be executed under the X window.
