Re: Get same position value in 2nd array

in reply to Get same position value in 2nd array

What frozenwithjoy said, but here's a first pass at something like what "... use hashes, but the look-up values themselves are actually variables made up of a scalar and a string of text appended to them ..." might look like:

>perl -wMstrict -le
"my $foo = 'Bar';
 ;;
 my %hash = ( 'BarBaz' => 'Quux' );
 ;;
 print $hash{ $foo . 'Baz' };
"
Quux

Update: Likewise for the OP second paragraph (but a hash might be better here):

>perl -wMstrict -le
"my @ra1 =   (   0,  1,    2,    0,     3,  -1);
 my @ra2 = qw(eeew  ok  fine  yech  great  bad);
 ;;
 RA1:
 for my $i (0 .. $#ra1) {
   next RA1 unless $ra1[$i] > 0;
   do_something_with($ra1[$i], $ra2[$i]);
   }
 ;;
 sub do_something_with { print qq{$_[0]: '$_[1]'}; }
"
1: 'ok'
2: 'fine'
3: 'great'
