I've already tried to do set! on lists and it did'n't worked out.
I assume that I must use set-car! or set-cdr! in order to change a list,
but if,for example i want to change a given list to a null one ( == '() )
how can I do that???

Well done.  This is the only news group I know in which a novice would
be treated so gently.

My response might have been something like 'buy a clue, buddy'!

Must be working with C/C++ weenies too much...
