Just for the sake of completeness:

If you want to access the first 10 values of the array, and leave them there, then an array slice is the way to go, as explained by hippo, 1nickt, and GrandFather.

But if you want to remove the first 10 elements into a second array, and then access them, use Perl’s splice function:

#! perl
use strict;
use warnings;
use Data::Dump;

# Populate @route with 100 strings: 'aa', 'ab', 'ac', ... 'dv'
my   $string = 'aa';
my   @route;
push @route, $string++ for 1 .. 100;

# Remove and print the first 10 elements
my   @first_ten = splice @route, 0, 10;
dd  \@first_ten;

# Print the remaining elements
dd  \@route;

Output:

13:05 >perl 1517_SoPW.pl
["aa" .. "aj"]
["ak" .. "dv"]

Hope that helps,
