My ver command responds with >DOS 4.01. IBM likes to issue things called a "CSD". This is the equivalent of what other software companies call "1.00" to "1.01" type version numbers. And let's make a distinction here: there exist 2 *real* flavors of DOS, MS-DOS from Microsoft, and PC-DOS from IBM. >Rick >rcm@hpctdpe.col.hp.com PS: I work for IBM, but the usual disclaimers still apply. -- Guy Lemieux ENG SCI University of Toronto guy@contact.uucp 9 T 2 Faculty of Applied Science and Engineering
