Thread-enabled SAS applications are able to create temporary utility files that can be accessed in parallel by separate threads. The size of this utility file is proportional to the amount of data that is read from the input data set.
A second utility file of the same size can be created in another of these locations when the amount of data that is read from the input data set is large or the amount of memory that is available to the SORT procedure is small. All rights reserved. SAS files are different from external files. Each SAS library has an access engine associated with it the first time that a file in the library is accessed.
The engine name specifies the access method that SAS uses to process the files in the library. Multi Engine Architecture also provides access to files created by other vendors' products, including database files.
The following sections highlight information you need in order to create and use SAS files with the various engines under Windows. Each member has a member type. For more information about engines, see Multi Engine Architecture. Also, you should not change the filename of a SAS file using operating system commands.
SAS creates temporary utility files that you do not need to access directly but that are necessary for processing SAS data. This section provides a brief overview of the concept of SAS data sets. Logically, a SAS data set consists of two types of information: descriptor information and data values. The descriptor information includes such things as data set name, data set type, data set label, and number of variables, as well as the names and labels of the variables in the data set, their types character or numeric , their length, their position within a record, and their formats.
