Hi ,

The arrays when input to a function will be obtained as a list and hence your first array alone gets assigned from the @_ , the array have to be passed as REFERENCE and then the return exits from the function and hence you can use only one of the returns and get the value from the calling part of it 
         use Data::Dumper;
         
         my @seg1 = ("fkgskfgskfgksf","kshflkshfkls");

         my @seg2 = ("kgskfgskf","sjfgsjfgjsgfksf");

         #create references 

         my $seg1 = \@seg1;
         my $seg2 = \@seg2;
         my $seg3 = \@seg3;
         my $seg4 = \@seg4;
         my $seg5 = \@seg5;

         my @pairs = get_pairs($seg1,$seg2,$seg3,$seg4,$seg5);

        print Dumper \@pairs;

        sub get_pairs {

            my @seg_pairs = @_;

            map {for my $i (1..scalar(@$_)){
                    push (@pairs , "$_->[$i-1] $_->[$i]\n");}
                }@seg_pairs;

            return @pairs;
        }

The usages of references are many and this is one of the ways to do it

the reference is pushed to an array and the array is passed to the function

the arrays are gotten by doing a dereference and then an array is pushed for that you should have

the array is obtained and the using Data::Dumper is printed and then you could do that you rerquire with it
