Remember that functions are global in IDL.

Write a function that creates your settings object and assigns it to a
system variable. On every entry to the function, check whether the system
variable exists and points to a valid object. If it does, use that object.

I'm sure there are other ways to do this, and some of them may even be
better than this one!
