getting the stack name of a library

[Michael Doub]

I am dynamically inserting a script into a stack to be used as a library.   How does an inserted function find out the name of the stack it has be inserted into?

I want to be able to create a custom property set for use by the library routines and I want that to be in the stack where the scripts reside.  

I am not sure that “me” is correct because that changes based on the object calling the library function.  

Can anyone provide guidance?

Thanks
