How?  I've been wanting to do that for years, so we could get something 
close to Gain Momentum's "View" objects but haven't been able to do it. 
Back in the day I asked Dr. Raney, and he told me it couldn't be done 
but that he might consider it for the future.

Has that future arrived?

I just tried it again in v4.6.4 and v5.5.1, with a mainstack "a" and a 
substack "b", in which "a" has a group named "x" and ran this in the 
Message Box with "b" topmost:

    place grp "x" of cd 1 of stack "a" into this cd

It threw this error:

    Message execution error:
    Error description: place: group is not in this stack or is
    already on this card

What's the secret?
