I thought that allowing undef in my ($a, undef, $b) came in around 5.004ish, but I can't find it in perldelta, and I don't have a version compiled to test with (or any quick way to compile them, given that pretty much only AIX is so stable that early perls compile unmodified. Probably someone will tell me that VMS is also good enough, for 5.002 or later) Nicholas Clark
