By declaring the arrays within a while loop, they are not accessible
outside the loop. That's why Perl complains. (Suggeste

The output is "kiwi", which is exactly right.

One more thing, those loops I was telling you about, just using a pair
of brackets, also keep their scope. It's a good way to clean up with
yourself, i.e.
my $foo = 40;
{
my $foo = 50;
print $foo; # prints 50
# garbage collector called on all declarations before here
}
print $foo; # prints
Lets say file 1 is:

bar
... continues on for 100 lines
And file 2 is:
foo
baz
bar
... continues on exactly the same 100 lines as file 1
Would file 2 be different from file 1 from line 2 and down? Or would it
be different for line 2 and 3?
Also, the keywords:

Hi all,
I have a file with several columns of numbers, that I want to make sure that
they are either increasing or are equal to the previously line - if not then
give a warning.
E.g.
my input file:
1 2
3 3
5 4
7 5
6 6 << Error in column one
8 7
I tried to do a foreach loop but cou
