Subject: WIN32OLE: Passing an Array

Dear Rubyists!

I'm trying to automate AutoCad 2002 via Win32OLE - since trying that kind of 
stuff with excel seemed to be quite easy I went on to try it with the next 
app :o)
Unfortunately I ran into problems after just 2 Minutes...

The following snippet of code works however:
require 'win32ole'
---
acad = WIN32OLE.new("autocad.application")
doc = acad.ActiveDocument
ms = doc.ModelSpace
puts " #{acad.name}, Version #{acad.version} "
---

When I'm trying to draw a line using:
---
koor1 = [1,1]
koor2 = [10,10]
ms.AddLine(koor1,koor2)
---
my program crashes with a segmentation fault.
I guess the problem lies in the arrays being passed to the method. I 
searched the web/usenet for any hints on how to pass an array to an ole 
object but found absolutely nothing.

Any hints?

Michael

P.S.: I'm quite sure that the Autocad-related stuff is right since i copied 
from a book about Autocad-VBA-programing
