In my most recent postings, I was dealing with first HoA and now HoH.

In my previous example code, I ended up with an output that looked
something like this:

jelly -- strawberry apple grape pear
jam -- strawberry apple grape
milk -- plain strawberry chocolate

I thought I'd prefer to have it listed more like this:

jelly -- strawberry
apple
grape
pear
jam -- strawberry
apple
grape
milk -- plain
strawberry
chocolate


So in the following snippet, I tried to add a "\n" onto the value of the
HoH.

for my $i ( keys %HoH ) {
%{$HoH{$i}} = join ("\n", %{$HoH{$i}}, "");
print "$i -- @{[ keys %{$HoH{$i}} ]}\n";
}

Try it like this:

for my $i ( keys %HoH ) {
my $key = "$i -- ";
print $key, join( "\n" . ' ' x length $key, keys %{ $HoH{ $i } } ), "\n";
}


This worked fine John. At first I didn't understand what was going on with the join, but after some sleep and looking at it more, I know understand it. Thanks much John!
