Well, (1) it is an ANSI standard, not subject to IBM's whim and (2) it would likely cause much consternation in the industry to break the standard. If nothing else, IBM would need to update every system of theirs which processes tape labels to be compatable with the new format. z/OS, z/VM-CMS, z/VSE, z/Linux (I think it can process SL tapes). -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
