perl mulitdementional array
 
i have a sub that returns an array like this

@x=array(array("1","2","3"));

not correct syntax, but it shows how it is returned. i want to travers through just the first element of array x. when i do
[CODE]
@y=@x[0];
foreach(@y){
print($_."\n");
}
[/CODE}

it will just print out somethign ot the extent of

ARRAY(0x98e2708)

but if i print

$x[0][1]

it will print fine... how can i travers though x[0]?

Effectively, you have to 'cast' the array ref $x[0] to an array viz:

Code:
@y = @{$x[0]};

for $item ( @y )
{
    print "$item\n";
}

you should ask what you want to do, not how you want us to do it.
there may be be a simpler way.
