creating and/or replacing stacks

[Lars Brehmer]

Can anybody point me to a tutorial or a demonstration or anything that  
emplains creating or deleting or replacing stacks from a standalone?  
What I want to do is make a standalone that updates another standalone  
by replacing one of its stacks with one from the updater stack. As  
basic as this probably is, I haven't a clue how to do it, and all  
atttempts to figure it out have failed.

Cheers,

Lars
