Mind you, I cannot for the life of me remember how to code that.
Calhoun's description there hints at how we could do this in LC:
In HyperCard 2.x, you can have only one stack
open but many card windows open -- the stacks
in inactive windows are actually closed, i.e.
the files on disk are closed. As I've
explained elsewhere, an inactive card window is
nothing more than a big button whose "script"
tells HC to "go to the card whose image is in
this window". When you click on such a window,
HyperCard activates it, closes the current stack,
and opens the stack in the newly active window.
You could write this in LC easily enough using:
import snapshop from <cardLongID>
The older snapshot syntax requiring a rect can only grab from the
current screen buffer, but the newer "from <object>" option causes a
fresh rendering of the specified object directly into the new image's
buffer - and those objects to not need to be open, or even in memory
yet, at the time that command it called. If it's a valid object
reference, it'll work for any object that has a visual appearance
(meaning cards and controls, but not stacks since a stack is an
abstraction whose visible element is a card).
Try it:
answer file "Select a stack file:"
import snapshot from the long id of cd 1 of it
