exit /b does not work properly in subroutines

[Martin Rakhmanov]

Hello

According to MSFT documentation (help exit) I expect "exit /b 1" called
within a batch to exit current batch and set ERRORLEVEL to 1. But this does
not work when I call exit /b in a subroutine - see attached batch. Why? I
am running Windows Server 2003 SP1.

How about this version?

- - - - - - - begin screen capture WinXP MCE 2005 SP2 - - - - - - -
=====begin c:\cmd\demo\sample.cmd ====================
01. @echo off
02. setlocal
03. set exit=goto :EOF
04. call :MyLabel %1
05. %exit%
06. echo This line should never be reached
07.
08. goto :EOF
09.
10. :MyLabel
11.
12. if NOT "%~1"=="unknownoption" (
13. echo Hello from subprogram
14. set exit=exit /b 1
15. goto :EOF
16. )
=====end c:\cmd\demo\sample.cmd ====================
- - - - - - - end screen capture WinXP MCE 2005 SP2 - - - - - - -

Thanks for input but this is not what I need: I should be able to quit
entire batch from within subprogram conditionally.
Also I do not understand why simple documented by Microsoft function ("exit
/b") does not work as expected.

It is doing what is expected. It is exiting the second bat file started with call. You are running a batchfile twice.

add this line

echo %errorlevel%
echo This line should never be reached

See Call's help.

Yes, you are right. How do I then exit entire batch from subprogram and set
errorlevel?

Also why exit without /b switch exits entire batch, i.e. does exactly what I
need (but does not set errorlevel)?

That's how programs tend to work. Return your error to main program, test it there and decide what to do.

It doesn't. It either exits a shelled batch or cmd.exe, just like all dos batch files expect..

 

[Martin Rakhmanov]

Please have a look at two batch files: they only differ in one line (exit
and exit /b 1 respectively). So why the batches behave differently?

Why do you keep repeating yourself. Are you a total idiot. I just told you.

 

[Martin Rakhmanov]

I see - /b switch is required to exit batch. Otherwise cmd.exe session is
closed. I have no more questions, thanks for help, David - it is excellent!

Thank you, you are so polite.

I realize that you have resolved your issue here, but it is worth
remembering the following truism: "when confronted with things that do not
work as expected, consider that it may be the expectation that is in error".
