Luc B. suggests that he got 1.0, but I could not duplicate the result
using Watcom under OS/2 (I don't use DOS).  When I ran the original
program, I did not get any error message.  However, when I tried to USE
THE VALUE OF "z" (for example, writing the value on the screen), I got
a nice error message "*ERR* KO-01 floating point divide by zero".
Note that the original program does not use the calculated "z".
Thus, I still believe I can use WATCOM (of course, level-B patched)
for serious numerical work.  My hardware is SWAN 486-50DX2 local bus
system.   Oh, if one suspects a hardware-related problem, I would suggest
that he may use f2c to check whether he can duplicate the problem.
BTW, f2c with GCC/2 2.2 is very nice and fast in floating point calc.
Although it is a little slower than WATCOM, it is not slower than
f2c with GCC/EMX in my experience (GCC/2 2.1 was a bit slower).
