You can assign multiple librefs to a
single directory, and specify a different engine with each libref.
For example, after the following statements are executed, data sets
that are referenced by
one
are created and
accessed using the default engine, while data sets that are referenced
by
two
are created and accessed using the
sequential engine:
libname one v9 '/users/myid/educ';
libname two v8 '/users/myid/educ';
Note: Keeping different types of
libraries in one directory is not recommended because you must remember
the appropriate engine for accessing each library. SAS cannot determine
the right engine for accessing libraries in a directory that contains
libraries of different types. For more information, see
Omitting Engine Names from the LIBNAME Statement.
