SAS(R) 9.1.3 Companion for z/OS

Functions and CALL Routines under z/OS MOPEN Function 269
SAS-data-library
specifies the physical filename of the SAS data library that is associated with the
libref.
Details
If the LIBNAME function returns a 0, then the function was successful. However, you
could receive a non-zero value, even if the function was successful. A non-zero value is
returned if an error, warning, or note is produced. To determine if the function was
successful, look through the SAS log and use the following guidelines:
3 If a warning or note was generated, then the function was successful.
3 If an error was generated, then the function was not successful.
If no value is provided for SAS-data-library or if SAS-data-library has a value of
’’(with or without a space), LIBNAME disassociates the libref from the data library.
DDnames (assigned by JCL or the TSO ALLOCATE command) can also be used to
refer to SAS data libraries.
Example
rc=libname(’v9dat’,’myapp.demo.v9dat’, ’v9’);
