Exit batch file from subroutine

How can I exit a batch file from inside a subroutine?

If I use the EXIT command, I simply return to the line where I called the subroutine, and execution continues.

Here's an example:

@echo off
ECHO Quitting...
CALL :QUIT
ECHO Still here!
GOTO END

:QUIT
EXIT /B 1

:END
EXIT /B 0

Output:

Quitting...
Still here!

Update:

This isn't a proper answer, but I ended up doing something along the lines of:

@echo off
CALL :SUBROUTINE_WITH_ERROR || GOTO HANDLE_FAIL
ECHO You shouldn't see this!
GOTO END

:SUBROUTINE_WITH_ERROR
ECHO Simulating failure...
EXIT /B 1

:HANDLE_FAIL
ECHO FAILURE!
EXIT /B 1

:END
ECHO NORMAL EXIT!
EXIT /B 0

The double-pipe statement of:

CALL :SUBROUTINE_WITH_ERROR || GOTO HANDLE_FAIL

is shorthand for:

CALL :SUBROUTINE_WITH_ERROR 
IF ERRORLEVEL 1 GOTO HANDLE_FAIL    

I would still love to know if there's a way to exit directly from a subroutine rather than having to make the CALLER handle the situation, but this at least gets the job done.

Update #2:
When calling a subroutine from within another subroutine, called in the manner above, I call from within subroutines thusly:

CALL :SUBROUTINE_WITH_ERROR || EXIT /B 1

This way, the error propagates back up to the "main", so to speak. The main part of the batch can then handle the error with the error handler GOTO :FAILURE
