汇编语言换行

Question

我是汇编语言编程的新手，我希望我的输出有单独的行，这样更容易阅读，但是，我编写了我的代码并使其运行，但随后被告知我实际上无法使用 Irvine 程序创建新行。我的教科书只使用 Irvine "Crlf"，而在本网站上提出类似问题的其他人的代码完全破坏了我的程序，所以现在我迷路了。

我尝试的一个是：

mov ah, 0Eh       ;print new line sequence
mov al, 0Dh
int 10h
mov al, 0Ah
int 10h

无论如何，这里是我的完整代码，仍然带有 Irvine 函数。有人可以帮助我在不使用 "call Crlf" 的情况下获得我正在寻找的输出吗？或者让我知道为什么上面的代码会破坏我的程序？我确定我缺少某些东西。

Answer 1

CRLF 只是添加到输出的两个字节序列，值 13 和 10。

如果你用这两个值创建了一个字符串，可能 prompt BYTE 'Hello!', 13, 10, 0 或者只包含 cr/lf 13,10,0 组合，你可以输出它而无需特殊过程。

Answer 2

为了扩展亚当的回答，这可能正是您正在寻找的内容：

carriageReturn BYTE ' ', 13, 10, 0

然后将其命名为：

mov edx,OFFSET report1       ;Display sum result
call WriteString
call WriteInt
mov edx,OFFSET carriageReturn ; new line
call WriteString

这样马车return在WriteInt
