How to loop through stacks with same name?

[J. Landman Gay]

You're right, though I assumed the stack names would be sufficiently 
unique. But your way is safer.

Regardless of the method, I have no idea why it isn't working for Håkan. It 
should. Håkan, did you check your LC preferences in Files and Memory? Try 
the various options.
