Yes WATCOM Fortran 77 can be installed directly in XP and
yes XP does run WATCOM 32bit DOS programs (have just used
DOS4GW extender ) . If you need to access ports,
do a web search on 'allowio' or 'porttalk'.
(If you need more than 1 port, separate the addresses by a space,
not comma! took me several days of head banging to figure that
out).
I use INT calls for screen control .. so they also work under XP.
(I just have XP pro -- but can't see why XP home would
be different for this purpose. Easy to test in any case.
Just download from www.openwatcom.org install and try.)
