The question was asked as to how to get BCX to work under Windows.

The answer: You can't.

The reason: BCX (and BCCX) incorporate built-in DOS extenders.  Said DOS
extenders are VCPI-compliant.  Windows is DPMI-compliant.  The two are
mutually exclusive.  Because BC[C]X is VCPI-compliant, however, it will
run under QEMM and the like.  Just now Windows.

TASM 2.5 _is_ DPMI-compliant, however, and will run just fine under Windows.

DPMI support will be forthcoming; however, it was not deemed necessary at
release time (according to the reports I've seen; I very much agree with
that assessment -- No matter what, compiling under Windows will be slower
that compiling under DOS).

To speed up BC's operation under Windows, set up a PIF file allocating
lots of _expanded_ memory, and have BC run with the /e switch (to use
expanded memory).  That should speed up its operation significantly.

Overall, though, I think you'd be better served by compiling under DOS;
it will be _much_ faster.
