That closing ')' should be a '}'.

Yes, it's certainly possible. What error did you get?

Something like this, below?
use strict;
use warnings;
my $HASH = {};
my $VAR = 'key';
my $number = 99;
$HASH->{$VAR}{letter} = "a";
$HASH->{$VAR}{$number}{float} = "1.1";
$HASH->{$VAR}{$number}{integer} = "2";
my $hash = $HASH->{$VAR};
foreach my $key (keys %$hash) {
my $value = $hash->{$key};
if ($key eq 'letter') {
printf "%s => letter %s\n", $key, $value;
}
else { # $key is a hash reference
printf "number %s => float %s, integer %s\n",
$key, $value->{float}, $value->{integer};
}
}
**OUTPUT
letter => letter a
number 99 => float 1.1, integer 2

I'm not completely clear on your problem, but I hope this gets you going.
