 Calling system functions, such as the system message box, requires understanding the arguments passed to them. As there is no direct assembler help, documentation of the Windows system API for C++ is helpful. Calling system functions, such as the system message box, requires understanding the arguments passed to them.

 Assembler code exposes functions to the linker using the ''global'' directive. Without it, assembler functions remain "private" and cannot be called, so linking won't succeed if there is a reference to the function from the high-level language part of the code. The following code presents a dummy function that performs integer addition of two arguments. Directives "section" are optional in this example. Assembler code exposes functions to the linker using the ''global'' directive.
