56 Assigning SAS Data Libraries Internally Chapter 2
3 DDnames that are allocated externally are not included in the list that is produced
by the LIBNAME LIST statement nor in the SAS Explorer window until after they
have been used as librefs in your SAS session. (See “Listing Your Current Librefs”
on page 61.)
Accessing SAS Data Sets without a Libref Using Quoted References
As an alternative to the libref.member syntax, it is possible to refer to some SAS files
directly by merely specifying the library and member name. This is supported even in
cases in which the library has not yet been assigned (such as via external allocation or
a LIBNAME statement). SAS automatically assigns the library, if necessary, when the
first reference to the library is made. The engine is determined by default according to
the rules described in “How SAS Assigns an Engine” on page 59.
Note: This method of identifying SAS files should only be used for SAS files that are
residing in libraries that can be allocated internally via a LIBNAME statement or
function and for which no LIBNAME options need to be specified. SAS determines
which engine to use by following the rules described in “How SAS Assigns an Engine”
on page 59. However, for SAS files in HFS libraries, it is possible also to specify the file
extension and thus control which engine should be used. This technique is described
below. R
Members of Direct Access and Sequential Access Bound Libraries
Members of existing direct access bound libraries and sequential access bound
libraries can be identified without a libref using the syntax below:
’(member)’
For example:
data ’user489.test.saslib(member1)’; x=1; run;
proc print data=’user489.test.saslib(member1)’; run;
If the value of the SYSPREF= system option was USER489, the following equivalent
syntax could have been used:
data ’.test.saslib(member1)’; x=1; run;
proc print data=’.test.saslib(member1)’; run;
Although the syntax is similar to the notation used for partitioned data set (PDS)
members, a SAS data library is not a PDS, and only SAS files can be accessed in this
manner.
Members of HFS Libraries
Members of new or existing HFS libraries can be identified without a libref using the
syntax below:
’’/member
If the library directory (that is, the lowest level directory in the specified path) does
not exist, SAS will automatically create it if possible.
The directory path can be fully qualified, as in the following example:
data ’/u/user905/MyProject/Member1’; x=51; run;
proc print data=’/u/user905/MyProject/Member1’; run;
