  | Thierry,
  |
  | I dont know about alternative shells but... (i use mostly NT
  | so, shell is
  | "cmd" but i've had no problems with command from w98)

I got problems on win98 with the command.exe !!!
but , I admit i'm asking for a lot :-)
What i tried whas to execute a perl script,
where the script is stored as a text in MC.
then just do shell( perl -e & quote & field "Perl" & quote ).
Sure, we have to set properly HOME and PATH directories for the dos.
I got amazing results... 10 lines

  | make sure your "directory" global is set to something that exists...
  | set the directory to "c:\"
  | If the directory is invalid, you will get errors even from
  | working commands.
  |
  | use of backslash or slash within the command shell should be
  | backslash...
  | Slash is only good in MC directory commands (but you can use backslash
  | AFAIK).
  |
  | Scott has told me that the "open process" works better but i've
  | had enormous
  | problems with compatibility and getting the whole output back whereas
  | shell() works great in all senses.
  |
  | With slow network connections, the shell() command can stall completely
  | though. This is really a bad problem because it causes major
  | problems in our
  | environment but for ALL other purposes, it's not a problem.
  |
  | Last but not least, remember that the path will affect the workings of
  | different programs you call from shell or open process, so providing the
  | path can help...
  |
  | shell( "echo $0 $1 $2"  ) worked great first time...
  |
  | here's an example startup script for you
  |
  | on openstack
  |   put the itemdelimiter into olddelim
  |   put the effective filename of the topstack into x
  |   if "/" is in x
  |   then get "/"
  |   else get "\"
  |   set the itemdelimiter to it
  |   delete last item of x
  |   put it after x
  |   set the itemdelimiter to olddelim
  |   set the directory to x
  |
  |   set the shellCommand to "cmd.exe" -- NT only
  |   set hideConsoleWindows to true
  |
  |   put "" into editMenus -- for the mac
  |
  |   CheckToolsAvailable -- dos tools required in the gui for
  | shell commands
  |   CheckUserIsAdmin -- user has the rights to work the tools?
  |   pass openstack
  | end openstack
  |
  | cheers
