How is "DD DUMMY" or "DD DSN=NULFILE" different from allocating a dataset which is Empty ?

DD DUMMY -> http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/iea2b600/12.24?DT=20010117171733

NULLFILE -> http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/iea2b600/12.22.2.9?SHELF=&DT=20010117171733
