You
will probably create and access libraries on disk more than any other
type of library. The default engine and the compatibility engines
allow Read, Write, and Update access to SAS files on disk. They also
support indexing and compression of observations.
In the following example,
the In libref is assigned to a directory that contains the Stats1
data set:
libname in '/users/myid/myappl';
proc print data=in.stats1;
run;
Remember, a
SAS-data-library must exist before SAS can read
from or write to this directory. For example, if you want to create
the SAS data set Orders in a directory, use the X statement to issue
the
mkdir UNIX command. Then, you can
use the LIBNAME statement to associate the libref with the directory:
x mkdir /users/publish/books;
libname books '/users/publish/books';
data books.orders;
... more SAS statements ...
run;
By default, the LIBNAME statement associates the
V9 engine with the directory.
