Aha! That's probably what I remembered seeing.
I guess what I was hoping I had seen was a way of using the "offset"
function with a from-right variation. Because it occurred to me that
I could then do something like...
put the short name of this stack into thisStack
put the long name of this stack into thePath
delete char (offsetBack(thisStack,thePath) to the length of thePath) of thePath
...and I would know that I was left with the correct path to a stack
even if the its long name were something like:
/PowerBook/MetaCard/MyStuff/MyStuff.mc
Never mind 8-(

David
