Overview:
In the SAS System, SAS I/O, the most common Input/Output (I/O) processing, is performed on SAS files such as SAS data sets, SAS catalogs, and SAS index files. Most SAS I/O processing is sequential I/O, which means that the DATA step and SAS procedures read a data set from the beginning of the file to the end of the file. The data is read from or written to pages that are typically 4 - 64 K in size. A SAS job can contain numerous DATA steps and SAS procedures that read and process the same data set or distinct data sets, or it can write or rewrite numerous new and existing data sets.
