| SAS Companion for the CMS Environment |
The SAS System provides
different engines
that enable you to access and, in most cases, to update files of different
types and different formats. See
SAS Language Reference: Dictionary for a complete discussion of the
types of engines that SAS provides on all host operating environments.
When you use the LIBNAME statement to assign a libref
to a SAS data library, you use the engine parameter to specify
the appropriate engine for each SAS data library that you want to access.
(See LIBNAME Statement Syntax.)
If you don't specify an engine, then SAS determines which engine to use by
following the procedures described in How SAS Assigns an Engine When No Engine Is Specified
.
If you use the CMS FILEDEF command to assign a libref
to a SAS data library, then SAS assigns an engine to the library. You can
override the default by subsequently using the LIBNAME statement to associate
a different engine with the library.
SAS Library Engines for CMS
lists the library engines that have
CMS-specific aspects and tells you where to look for more information about
them.
SAS Library Engines for CMS
|
Engine |
Description |
|
V7 |
accesses SAS files in Version 7 disk format. You can
also use the aliases BASE and V7. |
|
V7TAPE |
accesses SAS files in Version 7 sequential format on
tape or disk. The sequential file format is common among IBM host environments,
and sequential libraries can be shared among the CMS and OS/390 operating
environments. You can also use the alias TAPE to specify this engine. |
|
V6 |
accesses SAS files in Version 6 disk format. You
can also use the aliases V612, V611, V610, V609, V608, and V607 to specify
this engine. |
|
V6TAPE |
accesses SAS files in Version 6 sequential format, including
sequential format on tape and sequential format on disk. The sequential
file format is common among IBM host environments, and sequential libraries
can be shared among the CMS, OS/390, and VSE operating systems. You can
also use the alias V6SEQ to specify this engine. |
|
V5 |
accesses in read-only mode SAS files that were created
under Version 5 releases of SAS. You can also use the aliases V5TAPE to specify
this engine. |
|
BMDP |
provides read-only access to BMDP files. |
|
OSIRIS |
provides read-only access to OSIRIS files. |
|
SPSS |
provides read-only access to SPSS and SPSS-X files.
SPSSX is an alias for SPSS. |
|
REMOTE |
is used by SAS/CONNECT and SAS/SHARE
software
to access remote files. |
|
XPORT |
transports SAS files from one operating system to
another. |
Starting with SAS Version 7, the V606 engine is no longer
supported. If you have libraries that were created with the V606 engine, follow
these steps to access those libraries:
-
Invoke SAS Version 6.07 or later.
-
Use the COPY
procedure to copy the library.
-
Access the output of the COPY procedure in SAS
Version 7 or later.
