They have a VB Virtual Machine that will run VB5 Apps on any platform.
"How portable is Softworks VBVM?
Programs written in VB5 can be executed on a wide variety of operating
systems and hardware. VBVM has been ported to DOS, Windows 3.1, Windows 95,
Windows NT, BSDI, Dec Alpha, FreeBSD, IBM AIX (PS/2, PPC, RT, RS/600),
HP/UX, Linux, SCO, and SUN Sparc. We are looking for partners for ports to
AS/400 and MVS platforms.
VBVM is highly portable. It takes only a few hours to port to new UNIX or
POSIX platforms. We believe that VBVM can be targeted to any platform. Thus
our motto is "VBVM Everywhere".
