The above does not work because 'eq' is forcing the arrays into scalar context, therefore you are testing whether the length of the arrays is string (not numeric that would be C<==>) equal. But how to do this can be found in the FAQ, perldoc -q 'test whether two arrays or hashes are equal' perldoc perlfaq4, has some other juicy bits about analysing arrays and other data stores. http://danconia.org -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
