Show us some code and we will understand exactly what you are struggling 
with. I think I know, but it would be easier if
you give a specific short example.

You can create a closure using a list, or you could use a global
or you could just use a lot of parameters/return values. But
without seeing exactly what you are trying to do its difficult
to know which options suit you best.
