Batch files can not supress “terminate job”

Question

Im trying to open a 2nd batch file and detect if it normally exited or closed by a user (ctrl+c or x or window termiate etc..) so Im using this following example by Batch ru

Answer 1

This works for me:

call :runme start /w "Child Process" %comspec% /c "child.bat & exit 12345" NUL 2>NUL 
echo %ERRORLEVEL%
goto :eof

:runme
%*
goto :eof

The idea is to call a subroutine in the current script rather than calling out to an external script. You can still redirect input and output for a subroutine call.
