Re: array value generation for sections

Sure.

sub number_to_letter {
  return chr(96+shift);
}

But the hash isn't a bad way to do it. You can make the assignment much simpler:

my %h;
@h{1..18} = 'a'..'r';

Updated: fixed cut-and-paste-o whereby I had 'return' twice

I am just wondering why you use `return return`. If I would be at home, with Perl installed on the computer, I would have tested. My guess is that is has something to do with references. But I'm at school. No Perl here. So would you be so kind to explain? `"2b"\|\|!"2b";$$_="the question"`	[reply] [d/l] [select]

I think it is just a typo. It does compile OK with "return return" (which surprised me, actually) but it works just as well with just the one `return`. Update: If you consider that `return EXPR` is just an expression with the value `EXPR`, but with the added side effect of returning control to the caller of the sub, then it makes sense that you can put `return` as many times as you like. Including (in this case, since it's the last line of the sub) zero times. s^^unp(;75N=&9I<V@`ack(u,^;s\|$.+\`\|"$`$'\"$&\"$"\|ee;/m.+h/&&print$&;	[reply] [d/l] [select]
