What do you mean with array is empty??

• the @array-variable is not existing(exists)... does only work for single elements ... thanks for the hint moritz!
• the @array-variable is not defined
• the array has zero elements (if (scalar(@array) == 0) ...)
• each element is undefined my $empty = 1; foreach (@array) { $empty = 0  if (defined ($_)); } if ($empty) ...)
• each element is non-existent (similar as above)
• each element is 0 (similar as above)
• each element has a "not-defined"_value (similar as above)

Please select the appropriate solution for your requirements!
