in reply to What is this erroring out?

When the line return 0 if ($2 !~ /(d|p|t)/); is executed, $2 is undef because in the previous regex matching (the one in the line just above it!) has only one pair of parentheses. Use something like this (untested):

sub test { my $a = shift; my ($first, $second, $third, $fourth, $fifth) = $a =~ /(.)(.)(.)(.. +)(.+)/; return 0 if ($first !~ /(a)/); return 0 if ($second !~ /(d|p|t)/); return 0 if ($third !~ /(a|h|r|s|t)/); return 0 if ($fourth !~ /(aw|er|dd|cb|aa)/); }
