Hi Sitha.
As Rob Anderson points out, @AoA is an array of array references, not
an inherently two-dimensional array. However it may be worh pointing
out that
@var = splice @AoA, 2, 1;
is, as you say, removing the last element of @AoA and returning it. This
is the same as
@var = pop @AoA
but this will give you a new array with one element that looks like
@var = (
["EFG", "FGH"],
);
What you may want is to dereference this before you assign it to the array
like this
my @var = @{pop @AoA};
which leaves
@var = ( "EFG", "FGH" );
so you can say
print "@var\n";
getting
EFG FGH
as output.
I hope this helps.
Rob
