一个程序,高手指点一下
两个二位十进制数相加,以asc码存放在data1,data2 为首的五个内存单元,(低位在前),结果送回data1,以下是我的程序,运行结果很奇怪,请高手指点指点.
DATA SEGMENT
DATA1 DB '???'
DATA2 DB '??'
STRING DB 's is : $'
DATA ENDS
PUBLIC JISUAN
CODE SEGMENT
JISUAN PROC FAR
ASSUME CS:CODE,DS:DATA

MOV DS,AX
MOV SI,1

MOV AH,1

MOV DATA1[SI],AL
INC SI

MOV DATA1[SI],AL;低位在前我理解为低位地址低

[解决办法]
在JAVA版问汇编?
我汇编不好
