Re^2: How To Remove Warnings From Regex

Thank you Athanasius! That works perfectly. For as long as I can remember, I've avoided the backslash numbers in favor of the dollar-sign numbers, but I see in this case that is exactly what is called for. Thanks again.

`\1` works inside the regex where the capture group was defined. `$1` works everywhere else, i.e. in a replacement of a substitution. `$1` in a regex refers to a previously matched regex (which explains the uninitialized warnings). `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]

Thanks for the explanation choroba. It always helps to know the "why" behind the way things work. It makes it easier to remember in the future when a similar situation arises. Perl Monks are the best! "It's not how hard you work, it's how much you get done."	[reply]
