in reply to checking keys exist in 1 key:multiple value situation

The problem is with your data. What you might think are duplicate keys aren't really (the code which you showed would not do what you say, so $key must not be what you think it should be).

use Data::Dumper and print Dumper\%matrixhash to see what's actually in there. I'm guessing you have stray whitespace.

    hmm..maybe it's a different problem then. I used Data::Dumper like suggested
    and it printed:

    $VAR1 = { 'NERME' => 1 }; where NERME is a key and the first value I shove into its array is 1.
    Is this typical Data::Dumper "show me the hash" output ? It's the first
    time I've tried using Data::Dumper.
    Thanks,

      Yes, that is typical Data::Dumper output. Example 
      #!/usr/bin/perl
use Data::Dumper;
use strict;
use warnings;
my %hashes = ( 1..4);

push @{$hashes{z}}, 1..3;

die Dumper\%hashes;
__END__
$VAR1 = {
          '1' => 2,
          '3' => 4,
          'z' => [
                   1,
                   2,
                   3
                 ]
        };
