Hi, Paul.

PE> At the moment,
PE> 1. On a machine with no 80387 there is no maths functions.
PE> 2. On a machine with a 80387 there is no maths functions.

PE> It would be better if:
PE> 1. On a machine with no 80387 there is no maths functions.
PE> 2. On a machine with a 80386 there IS maths functions.

Why don't you just look at the code generated from one of your compilers
when you compile for 'copro present', then duplicate that? If C can't do
asm instructions (Turbo Pascal can) you might have to make external objs
with MASM or TASM.
