A SAS library is a collection of
one or more SAS files that are recognized by SAS, and that are referenced
and stored as a unit. Each file is a member of the library. An engine
is the software component that SAS uses to create, read, update, and
manage the files that reside in a SAS library. The topics in the following
list discuss the use of library engines and SAS libraries:
describes how to use
various types of engines under
z/OS to access SAS libraries. For the
base, sequential, and certain compatibility engines, the SAS libraries
can exist in various formats. For more information, see
SAS Library Engines.
Library Implementation Types for Base and Sequential Engines
describes the various
means for specifying that a particular library be used within a SAS
session. For more information, see
Assigning SAS Libraries.
See
SAS Language Reference: Concepts for additional general information about SAS libraries
and SAS I/O engines.
Note: If you are using files in
the UNIX System Services (USS) file system, then SAS views the UNIX
file system, the
z/OS file system (zFS), and the Hierarchical File
System (HFS) as functionally equivalent.
