Hallo Felix, thanx a lot :o)
... undef != $results[$i] ... is the correct syntax, it shall prevent accessing unexisting array elements. Have a nice weekend...

'undef' is an operator which undefines its argument, and always returns the undefined value. The expression 'not undef $results[$i] therefor will always be 'true', but in the meantime $results[$i] will become undefined. You probably want ... defined $results[$i] ... instead. -- felix -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
