Yes, you're right.  This is how I meant to define my array:

my @AoA = ( [ 1..12 ], [ 'A'..'L' ] );

Ok, what I need is for the AoA to be reformatted like this into another
AoA.


1st 4 columns(1-4,A-D), "empty column", Next 4 columns(5-8,E-H)
"empty row in AoA"
Next 2 columns(9-10,I-J), "empty column", Last 2 columns(11-12,K-L)

Does this explain it?

Thanks for any help you can offer.

BTW, this code is straight from Programming Perl 3rd ed. Chapter 9.

Thanks for your help!
