get values from a stack

[Peter T. Evensen]

I thought I remembered that one could get values from fields of a stack 
without having to open (or go to) that stack.  Is this true?

I have a stack with data.  This stack is never displayed.  Do I have to "go 
invisible" to the stack before I can get the value of fields in that stack?
