Of course I
have one more rookie question and a reference to a perldoc is just
fine. :~) If I use the following code, why do I not need to declare
the $a and the $b w/ my?
Correct. This is explained in perldoc perlvar:
$a
$b Special package variables when using sort(), see "sort" in
perlfunc. Because of this specialness $a and $b don't need to
be declared (using use vars, or our()) even when using the
"strict 'vars'" pragma. Don't lexicalize them with "my $a" or
"my $b" if you want to be able to use them in the sort() com-
parison block or function.
