I put the command 'echo off' at the top of most of my batch files to hide the following commands. However, 'echo off' is still displayed. Does anyone know how to turn off echoing in a batch file without showing the 'echo off?' Thanks, Marc Haverland haverlan@tramp.Colorado.EDU

There are however some patches which have gone around the net which allow command.com to be patched to make echo off the default. Unfortunately, I did not save the patches since I did not need them. There is a replacement for command.com called 4DOS which implements the @ECHO OFF correctly. Not only this, but it can swap itself onto disk, or expanded memory, is smaller and faster than command.com and has much better batch file processing and aliasing and environment variables which are useable, as opposed to those in command.com which are difficult to use at best. This package is put out by J.P. Software and they provide a 21day free trial version which is on a lot of BBS. I tried it and after 2 days, sent in my $50 (shareware) to register. This fee includes registration, next version free and printed manual. This is a really well done package and is worth every bit of the price. I don't have the address here at work now, but if anyone is interested, please E-mail me and I will look it up at home and get it out to you so you can order a free trial disk.

If you have DOS 3.2, or later, (I think it was 3.2) all you need to do is
put a @ as the first character before the echo off (@echo off). The @
suppresses output of that command line. If you have earlier versions of
DOS, the common why was to bugger DOS so that the default was echo off.

There was something in a recent PC Magazine about this. If memory
serves, the method used was to redirect all console output to NUL using
the ctty command, then explicitly direct any output you want to appear
on the screen to CON. eg. "echo Enter Y or N > CON". Be sure to use
ctty to redirect output back to CON before ending your batch file.

I hate to think what would happen if your user breaks out of the batch
file. Is it really that important to hide one line?

For those who have DOS 3.2 or lower, and are not excited about patching command.com or installing a replacement, the only answer I know of is to follow the "echo off" line with a "cls" line. The "echo off" is displayed, but it is erased so quickly it usually can't be noticed. This will usually suffice for all but the most "discriminating" nitpickers :-) :-) --- Michael J.

Oh well, for people who think that patching brain-damaged software is a
Good Thing to Do, here are the batch-file patches I've used, with
context. They've worked on MS-DOS v2.11 through v3.21, and might work
on later versions.
"Enjoy."
p.s. Two separate patches are involved. I was told that my description
of which patch fixes which batch file is backwards, but I can't remember
whether I updated the descriptions or not. Usually both patches are desired
anyway. Also, some miscellaneous patches and some notes are at the end.
____________________________________________
This file is basically an annotated script from a DEBUG session, plus
some appended trivia. If you can't figure out how to use DEBUG this
won't be very clear, but then it won't be much use either. For each
patch, I start by searching for a target string (that's the "s"
command). I unassemble the surrounding locations to be sure I have what
I want ("u"), then I change the indicated byte ("e").

Subject: COMMAND.COM Patch for Echo OFF Under DOS 3.1
I tried this patch on DOS 3.1. It works fine. However,
the RENAME command is affected too: it doesn't accept a path name
anymore for the first argument (it accepts only a file name in the
current directory). When I restored my unpatched COMMAND.COM, it
worked correctly.
Has anyone else had the same problem?
Jai.
[ I use a `mv' program which is much nicer anyway, so I'm not affected. - RAM ]

For earlier DOS, here is the technique I learned several years ago to patch the COMMAND.COM file on any version of MS-DOS or PC-DOS to make the initial echo status for BAT files OFF. It is reproduced from memory and some quick experiments, so no guarantees, of course. 1. Make a copy of COMMAND.COM and work on it. >COPY COMMAND.COM COMX.COM 2. Run DEBUG and enter the commands shown. (Do not enter the commentary) >DEBUG COMX.COM -s 0,5fff 24 01 Find the byte sequence 24 01. xxxx:1B2B DEBUG replies with addresses it finds bytes. -u1b18 Disassemble starting with previous instruction: xxxx:1B28 A0FC0A MOV AL,[0AFC] xxxx:1B2B 2401 AND AL,01 ... -e1B2C 00 Patch the 01 byte to 00 -s 0,5fff fc 0a 03 Find the address in the above disassembled instruction followed by the byte 03 xxxx:115C -u115a To check, disassemble the instruction: xxxx:115A C606FC0A03 MOV BYTE PTR [0AFC],03 ... -e115e 02 Patch the 03 byte to 02 -w Write the modified file -q Quit (The above addresses are from PC-DOS 3.21. The "xxxx:" depends on your memory use at the time you run DEBUG.) 3. Do a binary comparison of the COMX.COM and original COMMAND.COM files. Only the two bytes should have changed, 03 to 02 and 01 to 00. To test it, on a floppy formatted with the /S option, replace COMMAND.COM with the COMX.COM, renaming it COMMAND.COM. Then reboot with the floppy. If all works well, rename COMMAND.COM to some other name such as COMMAND.COX and COMX.COM to COMMAND.COM in your normal boot directory (As I recall, the first patch indicates an "echo off" status during execution of a BAT file statement. The second patch selects "echo off" as the initial status for an AUTOEXEC.BAT file. It's been several years since I've done this, so I may be slightly wrong on the reasons.)
