Access a permanent data set stored on a disk in SAS
Use the LIBNAME
statement to access SAS permanent data sets. Depending on releases, the extension of a SAS data set can be
.ssd
(version 6.04 for DOS/Windows), .ssd01
(version 6 for Unix), .sd2
(version 6.08 to 6.12),
.ssd04
(DEC machines), .sd7
(version 7 or 8), or .sas7bdat
(version 8 and later).
Suppose you want to read a SAS data set named
grade.sas7bdat
in the ~/data
directory. The following example shows how to retrieve a SAS data set:
LIBNAME stat '~/data';
DATA stat.new_grade;
SET stat.grade;
...
RUN;
LIBNAME
associates a SAS library reference (libref) with a directory. In this example, stat
is the libref that aliases ~/data
. In Windows, an alias consists of drive and directory names (for example, c:\data\
). The
SET
statement reads existing SAS data sets specified. This example tells SAS to read a SAS data set
grade.sas7bdat
from the library stat
, perform some data manipulation, and then write the result into
new_grade.sas7bdat
in ~/data
, which is associated with the library stat
.
