My point was that what you see in Linux and CMS are not two different things.. a Linux 'cat' and CMS 'TYPE' are pretty equivalent -- and a packed file looks garbled using either one.
I think Neale had a good idea in making the Linux 'file' command recognize this particular signature so at least Linux knows it is packed and not text format - just as it knows about tar, gzip, etc even without a particular filetype in the name.
