In actuallity... the 2 are almost identical to each other.
This is how they differ......
Alt+X memory stats for 'mem /c'
Conventional memory:
Name Size in Decimal Size in Hex
DOS 91,040 ( 88K ) 163A0
QEMM386$ 768 ( 0K ) 300
COMMAND 1,536 ( 1K ) 600
FREE 643,456 ( 628K ) 9D180
Memory Type Total Bytes ( Kbytes ) Available For Programs
Extended 15,728,640 ( 15,360K ) 0 ( 0K )
Extended via XMS -------- 6,804,480 ( 6,645K )
EMS 267,223,040 ( 260,960K ) 163,053,568 ( 159,232K )
Largest executable program: 643,440 ( 628K )
Total Free DOS memory: 741,712 ( 724K )
As we see... core.exe has been 'dumped' from memory upon exiting Arachne
and we must type 'arachne.bat<enter>' to restart Arachne.

Total Free DOS memory: 733,952 ( 717K )
As we see... core.exe has been 'dumped' from memory upon 'shelling-out'
from Arachne but a second copy of command.com was loaded via $roura$.bat
which 'calls' dosshell.bat
--- $roura$.bat ---
call l:\arachne\system\dgi\dosshell.bat l:\arachne\
arachne -r
____________________________________________________
--- dosshell.bat ---
@echo off
set oldpmt=%prompt%
set prompt=Type EXIT to return to Arachne$_$p$g
if exist ppp.log set prompt=You are still online$_Type EXIT to return to
Arachne$_$p$g
if (%COMSPEC%)==() goto nocomspec
%COMSPEC% /E:1024
goto end
:nocomspec
COMMAND.COM /E:1024
:end
set prompt=%oldpmt%
set oldpmt=
%1
cd %1system
cd ..
_____________________
Now we must type 'exit<enter>' to quit that 2nd copy of command.com
and Arachne is restarted via the next line in $roura$.bat which
runs arachne.bat automatically instead of requiring the user to
restart her manually via 'arachne.bat<enter>' on the command line.
________________________________________
Try this and see what happens....
Alt+E to 'shell-out'
Use a text editor to remove that 'arachne -r' from $roura$.bat
located in the arachne.tmp subdirectory under your temp dir.
--- mine is located here........
l:\temp\arachne.tmp\$roura$.bat
____________________
Save the altered file and quit your text editor.
Now you're back at the DOS command prompt and typing 'exit<enter>'
will quit that second copy of command.com but since the line for
restarting Arachne automatically has been removed from $roura$.bat
it will now be required to restart her manually by typing
'arachne.bat<enter>' at the command prompt.
