    You could detect some specifics, but you'd have to make a "smart" 
    assembler. Example, give the 'bler (assembler) a knowledge base
    of DOS interupt services. It can check if you've assigned the
    right registers for the service.
    You could try a "define before use" clause for registers. If a register
    has not been assigned a value (by declaration or by INT call), you could
    produce a warning that it may not be defined yet.
    You could try to define pairs of instuctions. Maybe warn if a "push"
    has no accompanying "pop" in a function macro. Warn if a macro destroys
    registers that haven't been saved (or pushed).
   
    If a well experienced asm writter could think of the common mistakes
    he makes, he could find some semantic warnings that would really fit
    the bill.
