I normally don't use DOS < 3.3 myself, either. But I do have programs that
claim to work with DOS 3.0 or 3.1 so I want to make sure they actually work
where they claim to. I guess hardly anybody really uses DOS < 3.3 any more,
except maybe the few people who still have working PC/XT/Jr

Actually, no it's not. It's fairly easy with System Commander. And AFAIK,
System Commander is the only multi-boot manager that works this way

That is definitely possible. Since the earliest version of DOS I really only
every used was MS 3.3, I never have worried about pre-3.3 compatibility.

Thanks everybody for the input! Lots of interesting suggestions/ideas.
I think the proposed solutions generally fall into four categories:
1. Always use ECHO OFF without the @ and don't worry about it
2. Try to fix the problem before it happens
3. Just let the problem happen and "fix" the

Once you have debugged ALL your batch files you can place `CTTY NUL' before

See below to find how to chain/call another batch file.
Place the 'CTTY CON' first so you don't forget!
You need to be sure there are no interactive

It seems trying to redirect the echo off command (at least under windows

Regular echo commands however do redirect just fine

Oh, one more thing...
It could also possibly be a one-liner, like so:
echo off | vgotoxy up | vecho /n /e
But, it will display all of that before erasure. Also, I have no idea if there
would be compatibility issues under some DOS platforms or their different
versions. But, it works fine in

Well, I guess I’ll put in two cents worth of a non-standard solution…
If you don’t want to have the “echo off” on the screen and don’t want to clear
the screen either, you can do it using two utilities in V8Power tools
(available and provided with FreeDOS).
It would look something this…

Why not use the @echo off syntax, then simply use the cls command to
clear the screen before moving on to the later pieces of the autoexec.
It then won't show the @echo off command onthe screen.
The caveat of course is that all driver messages also get erased, but
that may or may not be an
Hi Bret
The simplest solution is to use ECHO OFF without the @ at the start of your
BAT file. That will work everywhere. If you don't like seeing this line on
the screen at boot, you could run CLS after that.
I suppose another way to solve this is with a simple tool that detects the
DOS version.

Would it be feasible to throw together an "@ECHO.COM" application which would
manually execute a normal "ECHO OFF" line if the DOS version is below 3.3 and
simply terminate otherwise? The only caveat to this is that I''m not 100%
