If the LIBNAME function
returns a 0, then the function was successful. However, you could
receive a nonzero value, even if the function was successful. A nonzero
value is returned if an error, warning, or note is produced. To determine
whether the function was successful, look through the SAS Log and
use the following guidelines:
-
If a warning or note was generated,
then the function was successful.
-
If an error was generated, then
the function was not successful.
Under Windows, if you
do not specify a
SAS-data-library or if you specify a
SAS-data-library as ' ' (a space between single quotation marks) or '' (no space
between single quotation marks), SAS deassigns the libref.
