Exit in For loop - Windows Command Processor (CMD.EXE)

Question

Hi, I am trying to find way to break / exit from FOR loop, if there are any error occured. Below is content of batch file.

@echo on

set myfile=D:\sample.txt

FOR /F "tokens=1,2 delims=," %%i in (%myfile%) do call :process "%%i"

:process
set recfile=%1%

echo %recfile%
echo "Step in Test1"
echo %errorlevel%
pause;

exit /B 0
If %errorlevel% NEQ 0 goto :fail1

:fail1
echo "Step in fail1"
pause;
exit /B 9993

:EOF

Sample.txt has multiple records. If there are any error occured then I am expecting to exit the batch file rather then checking the complete sample.txt file. e.g. on statement echo %recfile%, If I place some wrong command ech %recfile% which is incorrect command then I am expecting that it should go to fail1 level and exit. It's catured the error code successfully and going to fail1 level however after this statment, it's checking the sample.txt file (next record) again. Is there any way, If I can break / exit FOR loop.

Please advice.

Thanks,

You can set a variable, meaning that the complete loop should be aborted and use it like this:

:fail1
echo "Step in fail1"
pause
set exit=1

And you'd change the loop like this:

FOR /F "tokens=1,2 delims=," %%i in (%myfile%) do (
  if defined exit (
    exit /b 9993
  ) else (
    call :process "%%i"
  )
)

(broken into multiple lines for readability).

Since you are just calling a subroutine from the for loop there is no way for this subroutine to exit the loop directly. Hence the workaround with a variable.
