急!那位大哥，请编写汇编程序，将数字码（0-9）转换成对应的ASCII代码！！！！

[sabbbin]

谢谢各位！！！！着急

[wjk302]

查表法也可以

[DragonBill]

MOV BL, 0
MOV CX, 10
LAB:
ADD BL, 30

MOV AH, 02H
MOV AL, BL
INT 21H

INC BL

LOOP LAB

[firstrose]

MOV AL,'0'
ADD AL,30H

[excuseser]

MOV AL,0
ADD AL,30H

[zhxk]

MOV AL,0
ADD AL,30H

mov al,3 ;以3为例
add al,30
如果是4就
mov al,4
add al,30

因为0-9正好对应ascii中的30h-39h,(1是31h,2是32h..)所以只要加上30就可以了.

[smzh8]

0-9转ascii码原理：x未知数 x-0+48的值就是ASCII码值

虽然，有点乱。但可以看，见笑了。

[我啃]

原理很简单,输入一个数值范围为0-9
则数值+'0'的ASCII码就是对应的ASCII码

[jiahu0215178]

上面是谁写的程序,没学过汇编吗/
怎么写这么多,cpu 执行你这样一个小的程序效率太差.
