Chris,

Once you make a reference to a stack, it is loaded into memory.  You 
can make sure that the user never sees it though by setting its 
visibility to false.  You do not need to use "start using".

For example:  put fld "data" of stack "externalStack.rev" to 
thisVariable

You would instantly (for the most part) have that data in your hands.
