I think it is an HX problem, so I'll report it to Japheth.

Subject: Re: [Freedos-user] CMDLINE
Sorry, I have to correct myself: According to
https://github.com/FDOS/freecom/blob/master/shell/init.c#L440
the REAL maximum possible environment size right
now is "only" 32766. Not 32767 and not 32768, but
FreeCOM texts (in all languages) claim it is 32768.
If you specify values below 17 or above 32766, some
default size of the environment will be used instead.
Regards, Eric
Hi Paul,
I believe that command.com can get involved in
the CMDLINE environment variable, just like any
other program can. And if it can't, it should say
so, rather than reporting a failed attempt to set it.
C:\DEVEL\PDOS\SRC>ver
FreeCom version 0.84-pre2 XMS_Swap [Aug 28 2006 00:29:00]
This seems to be the oldest version with CMDLINE at all:
https://github.com/FDOS/freecom/blob/master/CHANGED
Actually there seems to be a documentation error:
The REAL maximum value of 16-bit signed integers
is 32767 and not 32768 bytes. Try /E:16384 of, if
you are less humble, /E:32767 :-)
https://github.com/FDOS/freecom/blob/master/shell/init.c#L102
Regards, Eric
PS: I suggest to include a NEWER version in our distro!
