in reply to hash name as a variable?

Ronnie, I would set it up in a single hash like this:
my ($db, $key); my %DBs = ( "ISWLIVE" => { "LIVE1" => "/usr/local/bin", "LIVE2" => "whatever" }, "Next DB" => { "LIVE1" => "/usr/local/bin", "LIVE2" => "whatever" } ); # etc. for all your DB's and key/values

Then you can iterate through the keys of %DBs like this:
foreach $db ( sort keys %DBs ) { foreach $key ( sort keys %{ $DBs{$db} } ) { printf "DB = %s, key = %s, value = %s\n", $db, $key, $DBs{$db}->{$key}; # do whatever processing you want } }
