对不起打扰,我觉得很难理解的书
有什么区别在以下两种:
MOV AX,BX
MOV AX,[BX]
如果 BX
包含100H,和值在内存地址100H为23,做第二个副本,23 斧
?
此外,有什么区别
MOV AX,102H;移动102H的值写入寄存器斧
MOV AX,[102H]实际地址为DS:0 + 102H

是的。方括号之间的操作数视为一个地址,并在该存储器地址中的值,如果取
Sorry bother, I am find difficult to understand book
What is difference in the following two:
mov ax, bx
mov ax, [bx]
If bx
contains 100h, and value at memory address 100h is 23, does second one copy 23 to ax
?
Also, what is difference in
mov ax, 102h ; moves value of 102h into register ax
mov ax, [102h] ; Actual address is DS:0 + 102h

Yes. The operand between the brackets is treated as an address and the value at that memory address if fetched.
