需要有关 masm32 程序的帮助

Question

我只是汇编编程的初学者。这是我正在尝试的代码，但它一直返回错误。

错误是：

F:\masm32\bin>ml PRINTSTRING.ASM
Microsoft (R) Macro Assembler Version 6.14.8444
Copyright (C) Microsoft Corp 1981-1997.  All rights reserved.
Assembling: PRINTSTRING.ASM
PRINTSTRING.ASM(35) : fatal error A1010: unmatched block nesting : data

我的程序是：

;Print a String

data segment
;add your data here
mymessage db"Enter your data $"
end

stack segment
dw 128 dup(0)
end

code segment
Start:

;Set Segment Registers
    mov     ax,OFFSET mymessage
    mov     ds,ax
    mov     es,ax
    lea     dx,mymessage
    mov     ah,mymessage
    mov     ah,9
    int     21h

    mov     ah,1
    int     21h

    mov     ax,4c00h
    int     21h

end
end Start

提前谢谢你。

Answer 1

将.model small 添加为第一行。

Answer 2

首先，您为什么要进行 16 位 DOS 汇编？ 32 位组装更容易一些！

这行得通：

.model small
.stack 100h
.data
mymessage db 'Enter your data $'

.code
start:
    mov     ax, @data
    mov     ds, ax

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

    mov     ah, 1h
    int     21h

    mov     ax, 4c00h
    int     21h
end start

组装和链接：

在 DOSBox 中运行良好

Answer 3

试试这个

data segment

;add your data here

mymessage db"Enter your data $"

data ends

stack segment

dw 128 dup(0)

stack ends

code segment

Start:


;Set Segment Registers

    mov     ax,OFFSET mymessage

    mov     ds,ax

    mov     es,ax

    lea     dx,mymessage

    mov     ah,mymessage

    mov     ah,9

    int     21h


    mov     ah,1

    int     21h


    mov     ax,4c00h

    int     21h


code ends

end
