Thanks for that Chris.

I tried this on my Windows NT 4.0 system (service pack 6a) here at work and 
the command quoting works fine.

However I'm sure I've had a problem when it hasn't worked though.  I think 
that the quoting facilities provided in a DOS shell might depend on whether 
you are runing "pure DOS" or whether you are running a "DOS box" from a 
Windows GUI like Win95, Win98, WinNT or Win2000.  Until I get to my test 
machine at home I'll not be able to prove that.  My guess is that pure DOS 
won't provide quoting but DOS running _within_ Windows does but right now 
thats just speculation on my part.

Here is the program I used to test the quoting with:

-- argtest.ex

include get.e

function main()
  sequence cmdline

  cmdline = command_line()

  for i = 1 to length(cmdline) do
    printf(1, "Arg %02d is [%s]\n", {i, cmdline[i]})
  end for

  return(wait_key())
end function

abort(main())

If anyone wants to try this on a pure DOS machine with:

  ex argtest.ex "is this one argument"

then I'd be interested in the results.

FP.
