Hi Monks, <\p>

I am having a very large tab delimited file and I am trying to parse the odd and even columns separately. I have stored the first column in the array and want to store the rest of the columns in two separate hash of arrays or some other data structure so that I can compare them in a quick time. Can you please help in this regard ? Also, it will be great if you can advise me some data structure which I can use that doesn't have any problems in storing as what arrays has.

My code: 
while (<$outFile>) {
        chomp;
        $lno++;
        @line = split(/\t/, $_);
          ## $line[0] is for the first column
        push (@idmatrix, $line[0]) 
        if (0 == $lno % 2){
            ## Trying to store the even columns apart from the first c
+olumn values

            }
            else if (1 == $lno % 2){
            ## Trying to store the odd columns apart from the first co
+lumn values
            }
        }
    }
shift @idmatrix; 
## To delete the first row (Is there any other way to 
## delete the first row of the file)
