模拟与JMP的调用最好的办法（DOS组装） [英] Best way to simulate a call with jmp(dos assembly)

问题描述

我在Windows上使用平板汇编器和已经模拟了JMP CALL指令，但不知道是否有更好的方法以更少code办呢？（不使用电话）

I'm using a flat assembler on windows and have already simulated a call instruction with jmp but was wondering if there's a better way to do it with less code?(not using a call)

这里的code。

org 100h

mov al, 'x'

push come_back ; - simulated "call" -
jmp test_label  ; -   continued  -
come_back:     ; - end of simulated "call" -


mov al, 'y'

push come_back2 ; - simulated "call" -
jmp test_label  ; -   continued  -
come_back2:     ; - end of simulated "call" -

Looop:
jmp Looop


test_label:
mov ah, 0x0e
int 0x10
pop cx   ; - simulated "ret" -
jmp cx   ; - end of simulated "ret" 

这code只是显示屏上的XY，两个char的控制台。

This code just display's "xy", two char's to the console.

我不希望因为我wan't更好的理解，有时候，涉及处事错误的方式使用电话。
我是新来装配，不知道会是什么，去对此的最好方式。

I don't want to use a call because i wan't a better understanding, and sometimes that involves doing things the wrong way. I'm new to assembly and didn't know what would be the best way to go about this.

推荐答案

这可能工作：

push $+5
jmp fn
; no label needed here

一些组装机将跨preT $ 作为指令地址。

这是一个无限循环：

jmp $
