	I faced a similar situation where I had to remove all the objects 
from a list without disposing of them. ( I had two lists sharing some of their
objects, and I wanted to remove the objects from one list and still keep them
in the other.)

	What I ended up doing was write a RemoveAll method and add it to the
CList class. In this method I saved the number of objects in a local variable
and used that as my counter to remove the first item in the list that many 
times. It works fine. Watch out though because once you make this change,
your CList class is no longer the same as the CList that came with TCL.
And by the way, when you try to run the project, it will recompile every single
file included in the project.

	I hope this helps. I am sorry but due to Symantec's copyright I can not
publish the exact code for this method, but I think that there won't be any
problem if someone needed an e-mail copy of it.
