I have two batch files, task.bat and runtask.bat. The runtask.batcalls task.batand I would like runtask.bat to get the exit code of task.bat into a variable. How could this be done?
task.bat:
@echo off
set errorlevel=1
runtask.bat
...
CMD /C task.bat
set taskexitcode=????

EXIT /B at the end of the batch file will stop execution of a batch file. use EXIT /B < exitcodes > at the end of the batch file to return custom return codes. Environment variable %ERRORLEVEL% contains the latest errorlevel in the batch file, which is the latest error codes from the last command executed.
To display the exit code for the last command you ran on the command line, use the following command: $ echo $?
When used in a command line, script, or batch file, %1 is used to represent a variable or matched string. For example, in a Microsoft batch file, %1 can print what is entered after the batch file name.
I had a batch script in Teamcity pipeline and it did not exit after it's child script did exit with code 1.
To fix the problem I added this string IF %ERRORLEVEL% NEQ 0 EXIT 1 after the child script call.
main-script.bat
...some code
call child-script.bat
IF %ERRORLEVEL% NEQ 0 EXIT 1
...some code
After the child script call, exit result is save to %ERRORLEVEL%. If it did exit with error the value would be not equal to 0. So we check this and if it is the case we exit with code 1 (error).

Just swap CMD /C for call.
task.bat:
@echo off
set errorlevel=15
runtask.bat
call task.bat
set taskexitcode=%errorlevel%
echo %taskexitcode%
Output
15
