*blush* I'm afraid I'm the source of this disinformation. After sending that mail out, I had occasion to look into LSVXMAIL and LSVADD again, and found that what I recalled as hex data (a general term for anything which isn't comprised solely of printable EBCDIC characters) is in actuality just some mixed-case stuff out at column 100 or so. And Eric dropped me a line to say that the INSTALL FILE doesn't have any hex data in it either. Sorry, Ross
