You may be thinking, "Who cares!? I don't see why this is important."

Here is an example. Presumably the uvalue of one of these objects is
whatever I want it to be. It certainly works that way. So, I guess it
must be something that looks like a pointer. But, I want to have a user
value that I can transfer data into without making an extra copy of the
data. In other words, if I were going to put this in a pointer, I would
do this:

uvalue = Ptr_New(bigData, /No_Copy)

Is this possible with the uvalue in IDLitComponent (where I suspect this
is located)? If so, how would I do it?

Cheers,

David
