The word you want is "delete" but you will have to be careful. If you
delete an open mainstack, it is purged from memory without saving, but the
file remains intact on disk. However if you delete a substack, it is
removed from the mainstack and if you subsequently save its mainstack the
substack is gone forever. So you will need to delete the mainstack first
before opening the mainstack B that contains substack X.
If they are both open at the same time who knows which one will be targeted
for deletion.

If you have a stack open, say stack "A" and you open a different stack
file with a stack called "A", the IDE presents a message about stacks
with the same name and what do you want to do with essentially "Cancel"
(opening the new stack) or "Purge" (the old stack without saving) or
"Save" (the old stack and purge)
What does the IDE do to purge a stack?
I ask as I have the following case:
I have a stack open in the IDE (Call it "A") that uses another stack
(not a substack), call it "X" as a library stack. That stack needs to
make a scripted change to another mainstack (call it "B") with a
substack, also it "X", with the same name as the library stack (yes,
the naming could have been better, but these are old stack made by
different people and renaming stuff would be a real pain in the butt)
I have tried:
stop using stack "X"
set the destroyStack of stack "X" to true
close stack "X"
wait 0 with messages -- give time to close and remove the stack from memory
-- then open the other stack "X"
-- and do what I need
Yet when I try this, I get the IDE message about stacks of the same name.
Any tips on how to positively, absolutely purge a stack from memory?
