Question

我在8086大会上有一个非常简单的程序用于大学目的。主要组件正在工作，但是当我想显示2个或更多字符串时，我有一些特殊的字符，无法理解输出。这些是我在装配中的第一次尝试，因此可能出现很多错误，但我无法弄清楚这一点。

程序非常简单：首先显示消息＆＃34;欢迎使用我的三角区计算器！＆＃34;然后显示＆＃34;你想再试一次吗？是 - 是n - 否＆＃34;并且根据按下的键，您可以重试或完成程序。这是我的代码：

DATA SEGMENT PARA PUBLIC 'DATA'

WELCOME DB "Welcome to my triangle area calculator!$";welcome message

CONTINUE DB "Do you want another try? y-yes n-no$";other message

DATA ENDS


CODE SEGMENT PARA PUBLIC 'CODE'

ASSUME CS:CODE, DS:DATA

MAIN PROC FAR

MOV DX,OFFSET WELCOME;load the address of the welcome message in dx

MOV AH,09H; instruction for display

INT 21H; interrupt for display

XOR DX,DX; putting dx back to 0

XOR AX,AX; the same for ax

START:;loop label

MOV DX,OFFSET CONTINUE;loads the address of the other message into dx

MOV AH,09H; display intruction

INT 21H; interrupt for display

MOV AH,01H; character input instruction

INT 21H; interrupt for input

CMP AL,79H; comparison if the inputted character is y

JZ START; jump zero if it is

CMP AL,6EH; comparison if the inputted character is n

JZ FINISHPROGRAM; jump zero to finish the program

FINISHPROGRAM:

MOV AH,4CH; dos program ending

INT 21H

RET

MAIN ENDP

CODE ENDS

END MAIN

Answer 1

试试这个......

.model small
.data

welcome db 10,13,"Welcome to my triangle area calculator!$"
continue db 10,13,"Do you want another try? y-yes n-no$"

.code
       mov dx,@data
       mov ds,dx

start: lea dx,welcome
       mov ah,09h
       int 21h

       lea dx,continue
       mov ah,09h
       int 21h

       mov ah,01h
       int 21h

       cmp al,'y'
       je start
       mov ah,4ch
       int 21h
end
