        We are upgrading our old SCO Xenix system, but we would like
        to use our old applications in our new system. will SCO Unix
        be able to run SCO Xenix's programs, how stabile it is
        etc?

-- uname -a on SCO Xenix-system--------------------------------------
sysname=XENIX
nodename=host
release=2.3.1
version=SysV
machine=i386
origin=3
oem=3000
serial#=17402

   Old is right ... 2.3.1?  Even my home machine runs something slightly
newer than that (2.3.3 :-)

   If your apps are well-behaved, you should not have any problems.
If they try things like
- opening /xenix and looking through kernel memory
- reading directory entries by opening and reading the directory,
  rather than through OS calls
then you will probably have problems.

   But in general, all versions of SCO Unix run SCO Xenix binaries
(including those written for Xenix 286 and even Xenix 86) without
problems.

   I have a toolkit of some useful programs for Xenix and Unix.
They're all compiled for Xenix 386 2.3.x.  They all work flawlessly
on everything I've tried them on - Xenix 386 2.3.3, 2.3.4, Unix
3.2.2, 3.2v4.0, 3.2v4.1, 3.2v4.2, and OSR5.
