汇编语言编程求1*2*3*4*5*6*7，将结果存入fac中并显示出来。

以下是汇编语言实现求1*2*3*4*5*6*7的代码，并将结果存入fac中并显示出来：

include io32.inc
.data
fac dword 1
.code
start:
    main proc
        mov ecx, 1
        mov ebx, 7
    loop1:
        cmp ecx, ebx
        jg endloop1
        imul fac, ecx
        inc ecx
        jmp loop1
    endloop1:
        call dispdec
        call dispcrlf
        ret
    main endp
end main
