If your using C then remember to prepend your functions with an underscore C printf becomes ASM _printf If you are using C++ then you will need to follow the name mangling rules (I think). Arguments are passed to functions from left to right on the stack, so in NASM (assuming int args) [ESP+4] = first arg. [ESP+8] = 2nd arg on entry to your function. Most return values go in EAX. Floats probably go in ST(0) but I'm not sure. Andrew
