8086组装中的JMP与CALL [英] JMP vs. CALL in 8086 assembly

问题描述

我可以像使用CALL和RET一样使用JMP和RET从标签跳回吗?

Can I use JMP and RET to jump back from a label as you would with CALL and RET?

推荐答案

如果您想使用JMP代替CALL，但仍然使用RET或代替RET，则是一个更好的答案:

A better answer if you want to use JMP to replace CALL, but still use RET or as a replacement for RET also:

    PUSH WORD CS:Call_Return
    JMP My_Method
Call_Return:
    ... (cont)

My_Method:
    ...(some code)
    RET

或

My_Method:
    ...(some code)
    POP DX
    JMP DX

这只是证明可以用许多不同的方式来做同样的事情. 假定16位寻址(实模式)在这种情况下确实有所不同.在32位/64位寻址模式下，您需要相应地更改push，pop和JMP命令.

This just proves it is possible to do the same thing many different ways. This assumes 16-bit addressing (real mode) which does make a difference in this case. In 32-bit/64-bit addressing modes you will need to change the push, pop, and JMP commands accordingly.
