Re: [FishMonger] Print Hash Keys

Thanks to all of you Smile

Is it possible to have an hash key with character empty (" " or "") ?

In that case to erase it, should I use a loop:

Code

  if (($value1 != " ") && ($value1 != ""))  
{  
my $KeyHa = $value1;  
my $ValHA = 1;  
$Ha_ha{$KeyHa} = $ValHA;  
}

Or is it possible to execute the check while I assign the variable to the Hash-key?
