Again, for reference: IBM told me that saying DOS Version 4.01 was an error. They say that it is still DOS 4.00, with the CSDs applied. (Corrective Services Disks). It's apparently the public which use the number 4.01 and 4.02 to indicate that they have applied the CSDs. (that's what ONE person from IBM has said) Also, it might be worth noting that there have been (at least) two CSDs for DOS 4.00. I have applied both, and the ver command still responds with DOS 4.00. hh -- Harry Haas GTRI/RIDL/DB "What makes it DO that!?" - Bones Georgia Institute of Technology, Atlanta Georgia, 30332 uucp: ...!{decvax,hplabs,ncar,purdue,rutgers}!gatech!prism!hh2 Internet: hh2@prism.gatech.edu hhaas@{gtri01|rmadsun}.gatech.edu
