You'll probably need some operating system services to get that kind of functionality. Since that's a requirement, how would you do it from another language? Once you figure that out, you can just make the same calls from your assembly language program. Something like:

call OSServiceClearScreen

where OSServiceClearScreen is the name of the system call or library function that performs the operation you want. Then just link your assembly program with the right libraries and it should all "just work".
