Can a batch file capture the exit codes of the commands it is invoking?

Question

Basically, let's say that I have a batch file that calls myapp1.exe and myapp1.exe exits with Exit Code 1. Can the batch file capture this information and either force the batch file to exit with that same exit code or perform some other logic?

Answer 1

@echo off
rem ...
set errorlevel=
MyApp1.exe
exit /b %errorlevel%

would be the explicit variant.
