Need Help??

Sun751 has asked for the wisdom of the Perl Monks concerning the following question:

I have and array @ABC where each element is a hash, can some one suggest me if I want to find out number of hash key in last array element how can I do that?
I know that I can access the hash key of last array element through $name = $ABC::ABC-1->{'Name'}
Any suggestion?Please
Cheers

All these are equivalent `my $totalKeys = scalar keys %{$ABC[-1]}; my $totalKeys = keys %{$ABC[-1]}; my $totalKeys = 0 + keys %{$ABC[-1]};` [download]	[reply] [d/l]
