Data set options can be specified in
parentheses following a data set name. Each option applies only to the SAS data set whose name it follows. RENAME= and KEEP= are examples of SAS data set
options.
Some data set options can also be specified as engine or host options in the LIBNAME statement or function.
When one such option appears in a LIBNAME statement or function, it affects all data sets in that SAS data library. If the same
option is specified both in the LIBNAME statement or function and after a data set name, the SAS System uses the value given after the data set name. For more
information about the LIBNAME statement and about engine or host options, see
LIBNAME.
Some SAS data set options have the same effect (and usually the same name) as system or
statement options. For example, the BUFSIZE= data set option is analogous to the BUFSIZE= system option. In the case of
overlapping options, the SAS System uses the following rules of precedence:
For more information about SAS system options under
OpenVMS, see System Options.
When you specify a data set option, use the following
syntax:
|
data-set-name (option-1 = value-1 option-2 =
value-2)
|
For those options that are valid as engine or host options in the LIBNAME statement or
function, use the following syntax:
|
LIBNAME libref <engine>
'SAS-data-library'
option-1=value-1 option-2=value-2 ...;
|
Remember that not
all data set options are valid as engine or host options. Also keep in mind that it is usually better to specify an engine in the LIBNAME statement than to let
the SAS System determine which engine to use. This is important when you specify an engine or host option that is supported by two engines (for example, the ALQ= data set option) but which behaves
differently in each context.
