He probably just munged it a little from memory and transposed words &
numbers. Anyone familiar with sco would not have a problem mentally
correcting. I extremely doubt that anything anywhere in the entire system
claims to be greater than SVR3, but in some places they use the words
"release" and "version" a little inconsistently.

He has some version of SCO Unix 4.x
Whos full name is Unix System V Release 3.something Version 4.something
If the numbers above are correctly quoted at least as to their exact value
if not their exact position,
then I guess he has SvsV r3.0v4.0
I dont know if it was called "Open Server" at that point but just "SCO
Unix", or possibly "Open Desktop" But since I know there was and Open
Desktop 3.0, I guess since they were using the word "Open" at all they'd
probably have been naming the server release "Open Server" by then too. I
just don't recall ever hearing or seeing "Open Server 4" or "OSR4" before.

the "Version" is a SCO-added number and is free to climb to the sky.
the "Release" tells what main generation of "Sys-V" and is locked at
3.something (currently 3.2) as long as they use that codebase, no matter how
much they enhance it.

which lets you interpret the following from uname on a 5.0.6 box:
Release = 3.2v5.0.6
The 3.2 is "SysV r3.2"
The v5.0.6 is the version of sco's implimentation of that core sysv version

Unixware is not only SysV4 but actually SysV5 and is in fact the only SysV5
implimentation anywhere.

The very next version of OSR will be Unixware's kernel with the system
working like OSR. Whether that means OSR 5.0.8 will be sysv5 or not I'm not
sure. In-house they called it "FrankenServer" when they were first trying it
out. :)
