Hello: I am trying to create and access a
multidimensional hash.
For example the following works

$route {$routeDest} = $cost ;
print "$routeDest, Cost: $route{$routeDest}\n"

But the following does not print the
$route{$NODE}{$routeDest}
==========
$route {$NODE}{$routeDest} = $cost;
print "$route on $NODE cost:
$route{$NODE}{$routeDest};
==========
What am I doing wrong here?
Try something like:

$route{$NODE} = { };            # set node to contain a hash reference
$route{$NODE}{$routeDest} = $cost;              # then use
Does that help?
