转化后就可以显示了，转化算法很简单，你自己考虑
;将AL寄存器中的一位十六进制数转化成ASCII码，显示输出。
;程序如下：
ASSUME CS:CODE
CODE SEGMENT
START:
MOV AL, 0FH ;在这里可写 00H~0FH，这就是一位16进制数
AND AL, 0FH ;无用位清零，保留该数字
;下面是变成ASCII码
CMP AL, 0AH
JB NEXT
ADD AL, 07H
NEXT:
ADD AL, 30H
;下面是显示输出
MOV DL, AL ;送到DL
MOV AH, 2 ;显示单个字符
INT 21H ;显示
MOV AH, 4CH ;结束程序
INT 21H ;返回DOS
CODE ENDS
END START
1、将1A5Fh存入内存X中；
2、分四次将x取出放入AX中，对AX循环左移4位，将左移后的结果存回x中，再对AX取与求出其最低4位，这样AL中分别得出1、A、5、F；
3、将AL中存放的1、A、5、F分别转化为ASC2码（对0～9的加上30h，对10及以上的加上37H），再将其分别存入buf单元中；
4、使用09 DOS功能调用输出buf。
程序如下：
