多线程调用的是子程序我们都知道 子程序里也可以调用其他的子程序 但是有一点要注意：子程序里需要的变量（用到的变量） 必须在子程序里赋值 在主脚本里赋值，线程里会认为无效 也就是说 调用的子程序里的变量都会变成 该线程的变量 虽然变量名一样但是作用范围完全改变了-The multithreaded called subroutine we all know that the subroutine can also call other subroutines but one thing to pay attention to: subroutine variables (variables used) must be in the main scr ipt assignment assignment subroutine thread, the thread variable that the variable will become invalid That call subroutine variable name scope completely changed
