Willie, Regardless of whether you are building and AWS tape or not, when it is IBM Standard Label format, the details of the labels you generate must be as per the IBM specification documented herre (for R12 - later versions of the book exist) http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/dgt2m330/2.2.3?SHELF=EZ2ZBK0K&DT=20100701110050
