使用呼吁在一个批处理脚本标签

本文介绍了使用呼吁在一个批处理脚本标签的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

在使用CALL命令来调用批处理脚本标签，你最终的子程序与GOTO：EOF，从那里会发生什么？它返回到那里的子程序的CALL所在？或者它继续进行呼叫脚本的位置后？

When using the CALL command to call a label in a batch script, and you end the sub-routine with GOTO:eof, what happens from there? Does it return back to where the sub-routine's CALL is located? Or does it continue on after the location of the call script?

例如：

ECHO It's for my college fund.
CALL :OMGSUB
ECHO *runs away and cries like a little girl*

:OMGSUB
ECHO Your mom goes to college.
GOTO:eof

ECHO *picks up jewelry box*

GOTO后：EOF，这个线将是下一呼应

After GOTO:eof which line will it echo next?

推荐答案

为什么不运行它，看看自己？我救了你的脚本称为foo.bat一个批处理文件，我改变了你妈妈上大学前有一个回声。

Why not just run it and see for yourself? I saved your script to a batch file called foo.bat, and I changed the Your mom goes to college to have an echo in front.

C:\temp>foo

C:\temp>ECHO It's for my college fund.
It's for my college fund.

C:\temp>CALL :OMGSUB

C:\temp>echo Your mom goes to college.
Your mom goes to college.

C:\temp>GOTO:eof

C:\temp>ECHO *runs away and cries like a little girl*
*runs away and cries like a little girl*

C:\temp>echo Your mom goes to college.
Your mom goes to college.

C:\temp>GOTO:eof

C:\temp>

所以很容易地看到，经过了 OMGSUB 被调用，它

转到文件的末尾。

然后返回到线对AFER的 CALL：OMGSUB 和回声的逃跑行

然后再它的回声您妈妈行

将它转到文件结尾并终止的

回声的拿起jewewlry箱的线永远不会被达到。

Goes to the end of file.
Then it returns to the line right afer the CALL :OMGSUB and echos the "runs away" line
Then it echos the Your Mom line again
The it goes to end of file and terminates
The echo picks up jewewlry box line never gets reached.
