in reply to Size of a HASH (with more keys)

Use keys in scalar context:

my $count = keys %{ $testHash{$year} }

It might be better not to output the comma, though. Just invert the logic and print it before each sequence except the first one which is easy to detect:

my $first = 1; while (...) { print ',' unless $first; undef $first; print "..."; # print the sentence }

    I tried using your suggestion, but it didnt work. I am onto debugging, if something's wrong before with the Hash.
