I have a script that will read from a Tied file without problems.

But I'm missing something painfully obvious when trying to write to a tied file.

#!/usr/bin/perl
######################################################################
+############
use strict;
#use warnings;
use Tie::File;

popfileb();
print qq{DONE!!\n}
  or die 'unable to print to screen';

my @aod=();
my @aox=();
tie @aod, 'Tie::File', 'tmp/test.txt', recsep => "\n";
sub popfileb {
    foreach my $yb ( 0 .. 10 ) {
        foreach my $xb ( 0 .. 10 ) {
            #set first row;
            if ( $yb == 0 ) {
                substr $aox[0], $xb, 1, 'n';
            }
            #set increasing rows;
            elsif ( $yb > 0 ) {
                substr $aox[$yb], $xb, 1, 'a';
            }
        }
        $aod[$yb] = qq{$aox[$yb]\n};
    }

    return;
}
untie @aod;

exit;

The script runs but doesn't output anything to the file.

I've gone through all the examples I can find but can't seem to get a handle on this.
