mov ax, bx 与 mov ax, [bx]
下面两行有什么区别？
mov ax, bx
mov ax, [bx]
如果 bx 包含值 100h，并且内存地址 100h 处的值是 23，那么第二个是否将 23 复制到 ax？
另外，下面两行有什么区别？
mov ax, 102h ; moves value of 102h into register ax
mov ax, [102h] ; Actual address is DS:0 + 102h
What is the difference between the following two lines?
mov ax, bx
mov ax, [bx]
If bx contains the value 100h and the value at memory address 100h is 23, does the second one copy 23 to ax?
Also, what is the difference between the two following lines?
mov ax, 102h ; moves value of 102h into register ax
mov ax, [102h] ; Actual address is DS:0 + 102h

是的。括号之间的操作数被视为地址以及该内存地址处的值（如果获取）。
Yes. The operand between the brackets is treated as an address and the value at that memory address if fetched.
