convert scalar to an array

[NateBro]

ok, i tried looking for a post on here and came up with nothing.

what i'm trying to do is make an array inside of an array.

basicly the same as this...

  $array = [
               [1, 2, 3, 4] ,
               [1, 2, 3, 4]
            ]

but i need to do it some thing like...

  $array[1] = @array;

i have no idea how many entries will be inside of each sub array so ya, i'm lost, i know how to retrive them, but just not how to add them

thanks for any help you can give!

I think the following code is what you're looking for:

my @AoA;
while (<DATA>) {
    my @temp = split;
    push @AoA, [@temp];
}

__DATA__
a b c d
e f g h
i j k l
