The SAS/CONNECT client signs on to the SAS/CONNECT server named REMPC. A
server library is assigned to the client session. The value for SERVER= is the same as
the server session ID that is used in the SIGNON statement.
For more information about SAS/CONNECT, see SAS/CONNECT User’s Guide.
The SAS/SHARE client uses a LIBNAME statement to access a server library via the
existing libref, Sales, which was pre-defined at the SAS/SHARE server for client access.
libname sales server=server1;
For more information about SAS/SHARE, see SAS/SHARE User’s Guide.
Remote Library Access for WebDAV Servers
WebDAV (Web Distributed Authoring and Versioning) is a protocol that enhances the
HTTP protocol. It provides a standard infrastructure for collaborative authoring across
the Internet. WebDAV enables you to edit web documents, stores versions for later
retrieval, and provides a locking mechanism to prevent overwriting. SAS supports the
WebDAV protocol under the UNIX and Windows operating environments.
You use a LIBNAME statement to access WebDAV servers, as shown in the following
libname davdata v9 "http://www.webserver.com/users/mydir/datadir"
webdav user="mydir" pw="12345";
When you access files on a WebDAV server, SAS pulls the file from the server to your
local disk for processing. The files are temporarily stored in the SAS Work directory,
unless you use the LOCALCACHE= option in the LIBNAME statement, which
specifies a different directory for temporary storage. When you finish updating the file,
SAS pushes the file back to the WebDAV server for storage and removes the file from
the local disk.

Definition of Library Concatenation
Concatenation is the logical combining of two or more libraries. Concatenation enables
you to access the SAS data sets in several libraries with one libref.
You can concatenate two or more libraries by specifying their librefs or physical names
in the LIBNAME statement or function.
Physical names must be enclosed in single or double quotation marks in a LIBNAME
statement. Otherwise, SAS looks for a previously assigned libref with the same name.
In the following examples, Summer, Winter, Spring, Fall, and Annual are previously
libname annual (summer winter spring fall);
libname annual ('SAS-library-1' 'SAS-library-2' 'SAS-library-3');
libname annual ('SAS-library' winter spring fall);
