Maxi Monks,

My apologies for "yet another multidimensional array question", but I'm getting tangled up....

I want to build a 3-d array (list) like this. I'm extracting variables out of a large csv file and grouping them by var_0. I want to end up with:
var_0 = a var_1 var_2 var_3
  var_1 var_2 var_3
  var_1 var_2 var_3

 

var_0 = b var_1 var_2 var_3
  var_1 var_2 var_3
  var_1 var_2 var_3

 

var_0 = c var_1 var_2 var_3
  var_1 var_2 var_3
  var_1 var_2 var_3
So I tried (among other things) coded for clarity 
    open(FILE, $theFile) or die("cannot open file : $!");
    while (<FILE>) {
        $line = <FILE>;
        @line_parts = split (/\|/, $line);
        $var_0 = $line_parts[1];
        $var_1 = $line_parts[7];
        $var_2 = $line_parts[8];
        $var_3 = $line_parts[9];
        @tmp = ($var_1, $var_2, $var_3);
                push @{$theTable[$var_0]},  [ @tmp ];
    }
    close(FILE);

But this - and my many variations - isn't working. Could someone point me in the right direction?
