windows - Is there an easy way to capture the error code (%errorlevel%) from a nested batch script? -

i have nested batch script , want error codes percolate main batch script called it. have tried

exit /b %errorlevel% 

but variable doesn't make back. echo'ing %errorlevel% in called batch script gives me 103, echo'ing %errorlevel% in main batch script (the next line in terms of execution) gives me 0. question has been asked on before, none of posts have worked me.

edit: due poor writing, have revised question , add code see.

here main batch file. if statement here never hit unless change condition other 0:

call buildinstaller.cmd %sourcedir% %targetdir% %productversion% %%i if %errorlevel% neq 0 (     echo %date% %time%: build of %%i failed, halting >> %logfile%     exit /b %errorlevel% ) 

here buildinstaller.cmd exits. have cleaned prints avoid confusion:

if %errorlevel% neq 0 (     exit /b %errorlevel% ) 

as side note, tried doing

set returnvalue=12 

in called batch script, echo'ing %returnvalue% in main batch script 1 execution of program behind. if knows answer sub-question, cool know.

you have classical delayed expansion error. see example:

call buildinstaller.cmd %sourcedir% %targetdir% %productversion% %%i if %errorlevel% neq 0 (     echo %date% %time%: build of %%i failed, halting >> %logfile%     exit /b %errorlevel% ) 

this buildinstaller.cmd:

@echo off setlocal enabledelayedexpansion  if 1 == 1 (    rem inside code block, %errorlevel% have same value had before block    rem (its %value% not updated inside block) need use !errorlevel!    rem in order *updated* value     verify set errorlevel = 1    if !errorlevel! neq 0 (       exit /b !errorlevel!    ) )  exit /b
