Perl: nil, null, none, nothing, nada, 0, ...?

Back

I can never remember: "nil", "null", "None", "Nothing", etc. Each programming language is different....

In Perl, it's null In Perl, it's null

In Ruby, it's nil

In Python, it's None

In VB, it's Nothing

In C++, it's 0

In Java, it's null

# Usage example:
while ($entry != null)
{
    $entry->get_FileName($filename);
    print $filename->getString() . "\n";
    $entry = $entry->NextEntry();
}
