Hi, Thanks for the Map idea, I'm new to perl (but not other similar languages).
Can someone explain why the example:

map { $$_ = "null" if (!defined $$_); } @list_of_refs_to_vars_to_bind;

...uses $$_ when I would expect it to use $_ - i've googled round and round but haven't found an explanation yet.

many thanks
jonathan
