  [I missed this article the first time around. Thanks for bringing
it to my attention, Warner.]

   There are two approaches the poster could take. First, there's
Warner's RABIT program to insulate the Rainbow from Turbo C (or C++)
and its afinity for INT 18h. His is a neat approach, will work with
any version, but does require you to run RABIT beforehand. Second,
there are a variety of patches available for Turbo C (but not for
TC++, as far as I know) which force TCC.EXE to explicitly use
something other than INT 18h. Essentially, you change a few bytes
in TCC.EXE once and forget about it. If you upgrade to a different
version you must apply a different set of patches (if they exist),
but at least you don't have to worry about loading another program.

   You can find both Warner's RABIT and a patch set I developed
for Turbo C v2.0 in the INFO-DEC-MICRO file archives. For the
latter, look at TC2PATRB.ZIP in directory INFO-DEC-MICRO.PROG
on DRYCAS.CLUB.CC.CMU.EDU. [Patches for earlier versions of TC
were described in an article in _Rainbow News_, but I don't know
which issue.]
