What is the equivalent to $? in Windows?

Question

Does anybody know what is the equivalent to $? in Windows command line? Is there any?

EDIT: $? is the UNIX variable which holds the exit code of the last process

You want to check the value of %ERRORLEVEL%.

@echo off
run_some_command
if errorlevel 2 goto this
if errorlevel 1 goto that
goto end

:this
echo This
goto end

:that
echo That
goto end

:end

%errorlevel%
