Re: exit /b does not work properly in subroutines

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!

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?

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

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

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

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.

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.

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?
