Hi,
How can I test whether a hash is empty or not ?
For e.g: I have reference to a hash , say $preCommand and I get
$preCommands as {} ,
Its an empty hash, but it exists and is also defined.
I need to check whether the hash is empty or not.
Does anyone has any clue ?Regards, Suvajit -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
