Get error code from within a batch file

Sounds like you’ll want the “If Errorlevel” command. Assuming your executable returns a non-0 exit code on failure, you do something like:

myProgram.exe
if errorlevel 1 goto somethingbad
echo Success!
exit
:somethingbad
echo Something Bad Happened.

Errorlevel checking is done as a greater-or-equal check, so any non-0 exit value will trigger the jump. Therefore, if you need to check for more than one specific exit value, you should check for the highest one first.
