Why would you ever want to do that? DOS3.3 has a way to disable echo
selectively in the batch file. Why mess with patches?

Any line starting with @ is not echoed. Thus, if the first line
is @ECHO OFF, nothing echos. As for blank echos, if you put a dot
after the echo command (and nothing else) it just gives you a blank
line (as: "echo."). That's been in every version since 2.0!

I hate patching the system, and try to use existing features when possible.
I hate to admit it, but IBM listened on this one.
