I have been programmed assembly c= ode with "nasm" language.
in "nasm", when you refere to a function/label that come from ano= ther file, you should make a declaration of the function with "extern&q= uot; keywords in advance.
i don't know whether "at&t" assembly la= nguage is different with "nasm"?
thanks again!
