Hello Monks:

I need help with a slight variation of a code example I found in an O'relly book, regarding arrays of arrays.
(http://lux.e-reading.bz/htmbook.php/orelly/perl4/prog/ch09_01.htm#FOOTNOTE-1).

The book explains "we omit (for clarity) the my declarations that you would ordinarily put in."

The snippet I have reads a text file with the following content:

10 20 30 40 50
15 25 35
1 2 3 4 5 6 7 8 9 10


If I need the sum total from each line this would be the code where @AoA contains the above three lines: 

## Load values into the Array ###

$Test_File = "test_file.txt";

   open (TESTFILE, "$Test_File");
                    
          while (<TESTFILE>) {
          @tmp = split;           # Split elements into an array.
          push @AoA, [ @tmp ];    # Add an anonymous array reference t
+o @AoA.
          }


    close (TESTFILE); 

## Print the totals for each line ###

    for $i ( 0 .. $#AoA ) {
                   $row = $AoA[$i];
                   for $j ( 0 .. $#{$row} ) {
                        $Total_Balance[$i] += "$row->[$j]";

                   }
                print "the total is: ($Total_Balance[$i])<hr>";
    }

The output for the above code is:

         the total is: (150)
         the total is: (75)
         the total is: (55)


I need the same output but I changed the text file a little bit, (the row number is in the left and the value to add up is in the right), as follows:

1|10
1|20
1|30
1|40
1|50
2|15
2|25
2|35
3|1
3|2
3|3
3|4
3|5
3|6
3|7
3|8
3|9
3|10


For this example I only have three anonymous arrays but there could be 10 or 30 (unknown)
Thanx beforehand for your help
