Hello Everyone, I've included data in the example now and used strict and warnings, but I'm still not able to enter the if conditional; can anyone eluminate why this might be happening please?! many thanks in advance Dan 
#!C:\Perl\bin

use strict;
use warnings;

my @beginning = (34, 76);
my @ending = (72, 85);
my @interdomainatoms = (33, 34, 72, 73, 75, 76, 77, 78);
my $jcounter = 0;
my $nseg = 1;

    for (my $iseg = 0; $iseg <= $nseg; $iseg++){

        for (my $ires = $beginning[$iseg]; $ires <= $ending[$iseg]; $i
+res++) {

                if ($ires == $interdomainatoms[$jcounter]) {

                print STDOUT $ires;

                $jcounter++;
                }    
           }    
    }
