Re^3: Finding the sum of individual columns

split returns a list. Adding a list to a scalar does not really make sense in this context. Maybe you want a loop?

my @items = qw(1 2 3 4 5 6);
my $val = 10;
$val += $_
    for @items;

split returns a list. In list context but in scalar context it returns the number of fields in the list and puts the list into `@_` and issues a warning.	[reply] [d/l]
