in reply to Searching for two elements in two different lines

Just some humble comments:

foreach (@array_1) { chomp $_; }

can be written as

chomp @array_1;

Generally, there seems to be too much chomping.

Instead of

foreach my $element(@array_1) { if ($element !~ /^\s*$/) { if (($element =~ m/$output/) && ($element =~ m/$input/)) { #print +out all the matching output lines

you could

foreach my $element (grep { /$output/ && /$input/ } @array_1) {

Instead of

$join_1 = join (" ", "$input_1","$V_output","$marc_data","$marc_add"," +$stage_1")); push (@array_2,$join_1);

you could

push @array_2, "$input_1 $V_output $marc_data $marc_add $stage_1";

Instead of joining it into one string and then splitting it later again (hopefully the data does not contain any spaces...), you could store it in an array of arrays like this:

push @array_2, [ $input_1, $V_output, $marc_data, $marc_add, $stage_1 +]; # and later foreach (@array_2) { my ($input_2,$output_2,$data,$address,$stage_output_1) = @$_;
