To indicate which engine to use, you specify the engine name in the LIBNAME statement, as shown below.

LIBNAME libref engine 'SAS-data-library';

where

• libref is 1 to 8 characters long; begins with a letter or underscore; and contains only letters, numbers, or underscores.
  
  
• engine is the name of a library engine supported under your operating environment.
  
  
• SAS-data-library is the name of the SAS library where the file is stored. The specification of the physical name of the library differs by operating environment.

Interface library engines support read-only access to BMDP, OSIRIS, and SPSS files. With these engines, the physical filename associated with a libref is an actual filename, not a SAS library. This is an exception to the rules concerning librefs.

     libname rptdata spss 'g:\myspss.dat';

For more information on interface library engines, see the SAS documentation for your operating environment.
