Lele,

me too, and that won't change very soon. :-)
Variable initialization has more to do with clean coding than
correctness.

I just wonder where I took that line about variables keeping values
from previous invocations from; I'm sure I've read it somewhere but can't
remember any details (and no, Helen, I certainly wasn't arguing about
the scope of local variables ;-)).

Ciao
