Depends on what operating system you want to use. If MS-DOS version 6.X or earlier then you need to make it a TSR. There is quite a bit about that on the net, just google for it. MS-Windows doesn't use memory resident programs like that. It uses DLLs and device drivers, neither of which you would want to write in pure assembly. C or C++ are recommended languages for that. And if you do that, the code you posted simply can not be used at all because the os will not permit it.
