How can one batch file get another exit code?

I have two batch files, task.bat and runtask.bat . runtask.bat calls task.bat , and I would like runtask.bat to get the exit code of task.bat into a variable. How can I do that?

task.bat:

 @echo off set errorlevel=1

runtask.bat

 ... CMD /C task.bat set taskexitcode=????

Just replace CMD /C with call .

task.bat:

 @echo off set errorlevel=15

runtask.bat

 call task.bat set taskexitcode=%errorlevel% echo %taskexitcode%

Output

 15

The accepted answer is correct, but if you use call to call another batch of script, and this second batch of script uses SetLocal , for this you may need parsing. If you use this, add the following code before exit b :

 ENDLOCAL&set myvariable=%myvariable%

Now the value of myvariable becomes available to the calling context, and you can see its value in another script.
