Inline assembler call for subroutine

Question

I have question about inline assembler. It's possible to call another assembler subroutine from inline assembler within the same function? For example:

void FindValidPID(unsigned int &Pid) 
{
    __asm
    {
        sub esp, 20h
        mov eax, Pid
        add eax,eax
        call sub123 ; another assm subroutine
        mov Pid, eax
        add esp, 20h
    }
}

Where I should, and how, write subroutine sub123?

Cheers,
Thomas

If you are writing an entire subroutine in assembly, you should look into using the file-level assembler rather than inline.
