我目前正在编译DosBox中的汇编程序,但我一直有些错误 有人可以帮我修理吗? 我附上了我在MASM和链接上收到的错误的屏幕截图。
这是我的代码:
DATA SEGMENT
NUM1 DB ?
NUM2 DB ?
RESULT DB ?
MSG1 DB 10,13,"ENTER FIRST NUMBER TO MULTIPLY : $"
MSG2 DB 10,13,"ENTER SECOND NUMBER TO MULTIPLY : $"
MSG3 DB 10 ,13,"RESULT OF MULTIPLICATION IS : $"
ENDS
CODE SEGMENT
ASSUME DS:DATA,CS:CODE
START:
MOV AX,DATA
MOV DS,AX
LEA DX,MSG1
MOV AH,9
INT 21H
MOV AH,1
INT 21H
SUB AL,30H
MOV NUM1,AL
LEA DX,MSG2
MOV AH,9
INT 21H
MOV AH,1
INT 21H
SUB AL,30H
MOV NUM2,AL
MUL NUM1
MOV RESULT,AL
AAM
ADD AH,30H
ADD AL,30H
MOV BX,AX
LEA DX,MSG3
MOV AH,9
INT 21H
MOV AH,2
MOV DL,BH
INT 21H
MOV AH,2
MOV DL,BL
INT 21H
MOV AH,4CH
INT 21H
ENDS
END START
答案 0 :(得分:2)
MASM SEGMENT
指令的签名如下:
name SEGMENT [[READONLY]] [[align]] [[combine]] [[use]] [[characteristics]] ALIAS(string) [['class']]
statements
name ENDS
因此,您的代码包含汇编程序提到的两个错误:
DATA SEGMENT
NUM1 DB ?
...
ENDS ; This line should be: DATA ENDS
和
CODE SEGMENT
ASSUME DS:DATA,CS:CODE
START:
...
ENDS ; This line should be: CODE ENDS
所以你在'ENDS'指令之前错过了各自的名字,就是这样。
