大部分汇编代码由以下指令终止

MOV AH, 4CH
INT 21H

“MOV AH,4CH”是什么意思?

最佳答案

DOS中断int 21/4Ch为EXIT-TERMINATE WITH RETURN CODE,将al的内容用作返回代码,然后终止该过程。该文档随附以下注释:

Unless the process is its own parent (see #01378 [offset 16h] at AH=26h), all open files are closed and all memory belonging to the process is freed. All network file locks should be removed before calling this function
