assume cs:code,ds:data,ss:stack

data segment

db '4.modify        '
data ends

stack segment

stack ends


code segment

start:  mov ax,data
    mov ds,ax
    mov ax,stack
    mov ss,ax
    mov sp,16

    and al,11011111b
    inc si
    loop s1
    add bx,16
    pop cx
    loop s
code ends
end start
在mov ax,stack 和mov ax,data 这两行报错，不知道怎么解决。

自己做沙发。

难道是我masm配置的问题？

我刚刚问的，呵呵，又发现一个错error A4910: cannot open file: E:\masm32\bin\ml.err
刚安装的masm32为什么会找不到ml.err文件呢？

原版复制的。。。第一次用的是Radasm,换成Masm32参数没变，不知道咋变啊，没接触过masm32这个东西啊，求指教。

加上seg 还是那个错误。

知道错了，官方回答
you are trying to assemble and link a 16-bit program with a 32-bit assembler/linker
actually - the assembler should be ok - it is the linker that cannot handle 16-bit code
at the end of the sub-forum list is one for 16-bit programming
search that subforum
there are 16-bit linker downloads, as well as batch files to perform assembly and linking
there are also a number of 16-bit program examples
you do not have to declare all those segments - there are shortcuts   

then, the data segment is best refered to as @DATA

呵呵，谢谢，知道了
