windows批处理文件系统找不到指定的批处理标签-退出

Question

I'm having a problem with a DOS batch file and labels. I keep getting this error: there are two batch files(QQ.bat and Calling.bat) in the same folder.

the code of QQ.bat:

@echo off
set /a i=0
:loop
set /a i=i+1
echo %i%
c:
cd \Users
cd mytool
cd QQ
cd Bin
QQ.exe
if "%i%"=="2" goto exit 
goto loop

The code of Calling.bat:

@echo off
set/a i=0
:loop
set/a i=i+1
start /b cmd /c QQ.bat
if "%i%"=="4"  exit
goto loop
pause

the console's output "The system cannot find the batch label specified -exit",and excute severl QQ.exe by random and the amount is not correct ,while my excepted result is that there will be excute 8 QQ.exe simultaneously.

Answer 1

The console shows an error because GOTO statement is trying to jump to a label which doesn't exist.

From what I can understand by the use of goto exit in your script is that you want the script to exit at that point. For that use:

GOTO:EOF instead of goto exit .

Answer 2

This should do what your code is doing: QQ.exe is launched 8 times - but your code is reusing the %i% variable so you may not need it 8 times.

@echo off
for /L %%a in (1,1,8) do start "" /d "c:\Users\mytool\QQ\Bin" "QQ.exe"

Answer 3

You have correctly defined labels, but incorrectly interpreted goto syntax. Use "goto :exit" instead. You can find help on batch command by executing it with "/?" in command line (like "goto /?" )
