Re^3: substr outside of string

Your my is rather useless inside the "then" clause. May I recommend the following variation:

my $s = (length($str) < $index
   ? substr($str, $index, 1)
   : ''  # or undef, or die, or ...
);

Good point. I'd copied that line out of the original code and hadn't thought about it. Thanks for the catch. Hays	[reply]
