Thanks to both of you for your replies.  You've helped me identify the
problem.  I'm trying to assemble the code on an x86_64 system.  I
tried the code using two identical versions of as, except one was 64
bit and the other 32.  The assembly code assembled fine on the 32 bit.

So I don't know if the code simply doesn't work with the 64 bit CPU or
the language of the program doesn't work with the 64 bit assembler.

At any rate I tried:

$ as --32 power.s -o power.o

$ ld power.o -o power

and got

ld: warning: i386 architecture of input file `power.o' is incompatible
with i386:x86-64 output

I then found if I put ".code32" at the top of the code it compiled but
seg faulted.

I'll use the 32 bit machine from now on.
Thanks,
Kent
