    Though viruses are ultimately end up being binary, the actual code probably looks like this (except this code is completely innocent):

    mov ah, 1
    int 21
    sub al, 30
    mov [018F], al
    int 21
    sub al, 30
    mov bl, [018F]
    mul al, bl
    cmp al, 9
    jg 012F
    ...
    ...
