While I respect your opinion, I have to say that EVERY MVS site I have worked in (about 7) have a site standard that files must be allocated in JCL. This aids restartibility and means that operators with no SAS knowledge can easily see what files are used.

Personally I prefer LIBNAME. However, I am always working to my clients standards.

From an MVS viewpoint, I would suggest that aging DDNAMES are still the optimal way to allocate files in an MVS batch environment.
