用汇编语言打印出一个数字? [英] Printing out a number in assembly language?

问题描述

mov al,10
add al,15

如何打印al"的值?

推荐答案

你试过 int 21h 服务 2?DL 是要打印的字符.

Have you tried int 21h service 2? DL is the character to print.

mov dl,'A' ; print 'A'
mov ah,2
int 21h

要打印整数值，您必须编写一个循环来将整数分解为单个字符.如果你可以用十六进制打印值，这很简单.

To print the integer value, you'll have to write a loop to decompose the integer to individual characters. If you're okay with printing the value in hex, this is pretty trivial.

如果您不能依赖 DOS 服务，您也可以使用 BIOS int 10h 将 AL 设置为 0Eh 或 0Ah.

If you can't rely on DOS services, you might also be able to use the BIOS int 10h with AL set to 0Eh or 0Ah.
