That looks to be exactly what I need... If anyone was interested, here is what I've tried:

#  $frozen_cmd contains the command that provides the data I posted or
+iginally in the 'G' section
$ssh->send("$frozen_cmd");
my %frozen;
while ( defined ($line = $ssh->read_line()) ) {
     $frozen{$line} = '';
}

my $key;
foreach $key (%frozen) {
# $tmpcmd1 contains the command to look for just the specific entry of
+ "B" for that one group
     $ssh->send($tmpcmd1);
     my $frozhost = $ssh->read_line();
     $frozen{$key} = $frozhost;
}

I'll try your method out and see if that does the trick, but it looks like you got it.. Thanks so much!
