If you have a scalar that has a hash "in it" it would actually be a hash
reference. If you want to access a single key you can do this:
$hashref->{KeyName}
To access the hash as a hash, you must properly dereference it like so:
%{$hashref}
This is what I think you're looking for. For example now you can do this
foreach (keys (%{$hashref}) )
{
print "hash{$_} = ", $hashref->{$_}, "\n";
}
if all else fails check the following perl documentation:
perldsc - Perl Data Structures Cookbook
perlreftut - Mark's very short tutorial about references
