Perl is trying to tell you that statements like: my $x++ for(1..10); my $y = 1 if(1); might behave unpredictably in future version. what will be the value of $x and $y? you can try it and print their values out but don't be suprise that the behaviour will change in future version of Perl. david -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
