Better. As far as I am aware, Perl doesn't provide any guarantees on the order of evaluation of expressions between what C calls sequence points. Of course, Perl doesn't have sequence points, and has only one interpreter which generally works from left to right, but it's probably not good to rely on that. If nothing else it will screw you up when you write XS. Or maybe Perl 6 ;-) What does this print? perl -le 'print $i += $i++ + ++$i' Might is reasonably print something else? -- Paul Johnson - [EMAIL PROTECTED] http://www.pjcj.net
