If you know you only want one element from the array, use the dollar sign. At sign is for two and more, e.g. @total[1, 2].

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

Hey Chroba, thanks for responding. Yes I use strict and warnings. I meant to delete those lines of code because they didn't work. I had them commented out.	[reply]
