Read stdin stream in a batch file

Is it possible to use a piped stdin stream inside a batch file?

I want to be able to redirect the output of one command into my batch file process.bat list so:

C:\>someOtherProgram.exe | process.bat

My first attempt looked like:

echo OFF
setlocal

:again
set /p inputLine=""
echo.%inputLine%
if not (%inputLine%)==() goto again

endlocal
:End

When I test it with type testFile.txt | process.bat it prints out the first line repeatedly.

Is there another way?
