>Why are we talking about this? I've forgotten. For me, DOS is
a Microsoft/PC product, XyWrite was developed for DOS, and that
makes 64-bit backward compatibility a Windows issue,
overwhelmingly. The Subject line says it all. Linux use of
XyWrite strikes me as a niche issue, Mac use probably has more
traction but still in a niche.
What Xy for DOS needs is some kind of portable DOS environment. Virtual PC is a
Microsoft-supported product that comes with Win 7. There are different flavors
and support for Windows 2000 onwards. Many of us are still using 32-bit XP, but
a DOS virtual machine prepared today is ready for use in a 64-bit environment.
Virtual PC works like a browser for virtual hard disks and 16-bit EXEs. While
support for DOS has been phased out, you can still install Virtual PC 2004 DOS
Additions under Virtual PC 2007. The ubiquity and portability of this solution
makes it a strong contender. Setting it up is a bit tricky, but if you know how
to install a DOS computer with Win 3.11 with oddball hardware (virtual device
drivers), you can manage it.
Other free virtualization solutions include http://www.virtualbox.org/, but DOS
is poorly supported. "Presently, VirtualBox runs on Windows, Linux, Macintosh
and OpenSolaris hosts and supports a large number of guest operating systems
including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista,
Windows 7), DOS/Windows 3.x, Linux (2.4 and 2.6), Solaris and OpenSolaris, and
OpenBSD. "
And then there are Parallels and VMware, which are important on Intel-based
Macs.
