For those who are still battling path length and lack of environment space, here is some usefull info. In this months PC Magazine there is an article dealing with this subject, exactly, page 421 of the August issue. In it is says you can change your environment space by using the following command in your CONFIG.SYS file.. shell=c:\command.com /P /E:512 where COMMAND.COM is in the root directory of the c drive and 512 is the amount of space you want reserved for your environment. I have used it, I was given the traditional warning about envir.. space before but not after. The article also gives some references to look at if you are more interested in what is going on here. This may not be the ultimate solution, but then again.. :^). If there is something major that I am overlooking someone in the know can correct me. later... kevin -- ************************************************************************* Kevin Tomasek kevin@neptune.amd.com AMD - Advanced Micro Devices, Austin, Tx (512)462-5381 *************************************************************************

Most people here seem to know about the /E: option by now, which will increase the environment size. However, this will still not allow a PATH of more than about 122 characters regardless of what size environment you have. This is due to the PATH being set by entering a command line such as: PATH c:\dos;... which is limited to 127 characters max under DOS. Even tricks such as SET PATH=%PATH%;more;stuff... will not work as they are expanded inside a 127 character buffer internally. To set a PATH longer than this, watch for the APPENV.COM utility (with source!) soon to be posted in comp.binaries.ibm.pc (it is in the queue now). -Mark

In my original followup, I posed the question as to the validity of the
second parameter of the given SHELL parameter. For example, to expand
environment space to 640 bytes in DOS 3.2 or 3.3, the documented
command is:
SHELL=c:\command.com /p /e:640
whereas the original posters gave this form:
(where command.com in c:\dosdir)
SHELL=c:\dosdir\command.com c:\dosdir /p /e:640
note the additional second parameter: the directory in which
command.com resides.
My findings:
1) I cannot find this documented *anywhere*, even though several
people claimed that it is "clearly documented under COMMAND".
I checked PC DOS 3.2, PC DOS 3.3, and variants of MS DOS 3.1,
3.2, and 3.3. Nowhere could I find it -- not under CONFIG.SYS,
under COMMAND, anywhere. Checked IBM, Zenith, and Tatung manuals,
(Zenith usually being the most thorough of the DOS manuals I see).
2) It appears to work for any DOS 3.1+ (presumably 3.0 also?).
I tested with variants of DOS 3.1, 3.2, and 3.3. Worked fine
in every case (allowing for the different environment size
notation for DOS 3.1 -- paragraphs instead of bytes).
Every machine booted properly and left COMSPEC pointing to the
proper file name. This allows you to move command.com out of
the root, where I suppose it is more easily found by worms...
Thanks for the help, everyone. Informix database products customers:
this will be noted in the next release of the DOS Products Installation
Guide and Release Notes.

Ahem. From Zenith's MS-DOS Version 3.21 User's Reference, p. 3.31:
Syntax:
command [drive:][path][cttydev][/e:nnnnn][/p][/c string][/d]
Comments:
...
The drive:path options tell the command processor where to look
for the COMMAND.COM file if it needs to reload the transient
part into memory.
It doesn't really jump out at you, and it wouldn't be documented under
the config.sys section as it doesn't pertain to config.sys as such but
rather to command.com (which happens to be commonly specified in
config.sys). But it is there.rogers@SRC.Honeywell.COM (Brynn Rogers) (08/24/89)

Question: Can I have my command.com reloaded from RAMDRIVE? In other words, will SHELL=c:\dos\command.com g:\bin\command.com /e:3072 /p do what I want? Assuming G: is my ramdrive and my autoexec.bat copies command.com to G:\bin, of course. I already copy the most often used commands to the ramdrive, which is first in my path, and it gives a noticeable improvement to things like ls and xcopy. (DIR ? who uses DIR?)

"Ahem." :-) I don't know about "MS-DOS 3.1" manuals; I have "MS-DOS Version 3" manuals, but the disks give an OS that claims to be v3.1 --- and in the manuals, volume II, p. 11.76, COMMAND is described with these same parameters. However, I grant that the description in v3.1 reads differently from the v3.21 description. (Personally, I believe that this reflects Zenith's increasing understanding of undocumented behavior in the OS and doc. that they received from Microscum.) For what it's worth, the same syntax is shown, with a sketchy and not-too-helpful description (that could be saying *anything*) in the version 2.11 doc --- "MS-DOS Version 2", p. 11.75 disclaimer: I haven't had this much fun since my last stare-down contest with a kitty cat. I'll correct any speeling errors as soon as I look back at the keyboard....

I missed it the first time because I was looking for two pathnames, e.g. the typical SHELL=[d][path]command.com [d][path] ... but on this page, it just says COMMAND [d][path] ... anyway, I will offer in my defense that the section on SHELL mentions nothing of this. Also, I'd still like for one of the 4 or so people who insist that it's in the PC-DOS 3.X manuals point it out to me...
