Hello Monks,

I'm trying to assign the values from a couple of 2-D Arrays into a hash based on a "key" within the array.
I haven't messed with hashes in a while so I'm a little rusty. I'm having trouble figuring out how to assign the values, I looked for an example online but alas Google has failed me lol...

What I have is 5 separate 2-Dimensional Arrays. All arrays have the same setup.
For Example: @myArray[key][value]
### I'm using 5 separate arrays but for the sake of space I'll just do
+ 3 here...

$first[0][0] = "111"
$first[0][1] = "on"
$first[1][0] = "222"
$first[1][1] = "off"
$first[2][0] = "333"
$first[2][1] = "null"
...etc...
############################
$second[0][0] = "111"
$second[0][1] = "10.1.1.1"
$second[1][0] = "222"
$second[1][1] = "12.1.1.1"
$second[2][0] = "333"
$second[2][1] = "13.1.1.1"
...etc...
############################
$third[0][0] = "111"
$third[0][1] = "12.1(SAG1)"
$third[1][0] = "222"
$third[1][1] = "12.4(FCL5)"
$third[2][0] = "333"
$third[2][1] = "12.1(5)"
...etc...
############################


### Then have a hash with all the values combined.
# i.e. the hash should look something like this after a 'Data::Dump':

#--------- %all_data ---------#

VAR1 = '111' => "on",
             => "10.1.1.1",
             => "12.1(SAG1)";

VAR2 = '222' => "off",
             => "12.1.1.1",
             => "12.4(FCL5)";

VAR3 = '333' => "null",
             => "13.1.1.1",
             => "12.1(5)";

I'm having trouble figuring out if I need a loop or what not, because not all the arrays are the same length.
Occasionally a couple of the arrays might have more than one value for a particular key...
i.e. It might have 2 values like this below for the key "111".
$fourth[111][125]
$fourth[111][200]


If anyone has any hints that could point me in the right direction that would be great...
I've read the PerlDocs on hashes but I am still a little confused.


Thanks in Advance,
Matt
