Suggestion for lines on investigation welcomed

OH Chilly Monk,
If I want to know the number of elements in an array I'd try one of two things:

#  assume two arrays with a number of elements
#   @rray1 & @rray2

my $elements_1 = scalar @rray1;
#  or
my $elements_2 = $#rray2 + 1;

Either of the two will work.
