You should probable not call ref in this way. If $c had held a reference to an array it would have printed REF instead of ARRAY. Non reference values return undef when passed to ref. If you see SCALAR that means the value is a reference to a scalar. If you really want to see output you should say something like this: perl -MLWP::Simple -le '$c = get "http://3.am";print ref $c ? ref $c : "SCALAR VALUE"' -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
