Using SAS Engines

Overview of the SAS Engine

The SAS engine is used to create SAS libraries on disk and to read from, write to, or update those libraries. These engines support indexing and compression of observations.

Valid SAS engines in SAS 9.2 are: V9, V8, V7, and V6. The V9 engine is the default engine for new SAS libraries, unless the default engine has been changed with the ENGINE= system option. For more information, see ENGINE= System Option: OpenVMS.

The V6 engine is a read-only engine. For more information about this engine, see The V6 Engine under OpenVMS.

Note: Starting in SAS System 9, SAS is a 64-bit application. Previous releases of SAS have been 32-bit. Consequently, the V9 engine cannot read the 32-bit SAS files created in previous versions of SAS. For more information, see Compatibility of Existing SAS Files with SAS 9.2. [cautionend]
