Hi Eric.
I went to github, but the readme didn't show the "/e"
parameter. I looked around in the "docs" and "cmd"
but nothing stood out. I don't want to report a bug
unless I can see the documentation myself that says
32768. Currently I only see it when I go command /?
on my version which is presumably old.
Anyway, your theory is correct. ECX increases by 1
if I add another character to the command line. I have
already raised a problem with HX, so we'll see what
happens.
BTW, I'm a bit surprised this hasn't been found a long
time ago. HX + doslfn + Freedos gives you a free
Windows-compatible environment. Surely there is
some demand for this? The only thing I know of that
is missing is msvcrt.dll. I provide one of those with
PDPCLIB, but it only has C90 functionality. Not sure
if someone else provides the msvcrt.dll that Wine
must be using, for Freedos.
Note that I provide another Win32 environment
with PDOS/386.
BFN. Paul.

Hi Paul,
Thanks Eric - 32766 solved the problem!
Good, could you file a ticket on that github to
update the documentation to stop saying "32768"
instead of the correct 32766? Thanks! :-)

That would be "rep a16 movsb" if the task is 32-bit?
If the GPF is caused by ESI=EDI=100, maybe the "FF"
in the description of ES refers to segment length?
Which could mean a pointer overflow?
Does the ECX in the error message get larger when you
make the command line longer? If yes, it could mean
that something tries to copy the over-long command
line into the PSP?
I think it is an HX problem, so I'll report it to Japheth.
No idea, but you could use another DPMI provider, such
as CWSDPMI, which would be the default for DJGPP?
Regards, Eric
