I am learning...

I didn't see that  directive (.code 16). I have attached the intermediate
files and the commands used to compile, with this mail so that you can
also take a look at the file. It did compile properly when I added that
directive before the function definition. 

So that's the real Bug.

mail me if you need anything else
