in thread How can one create an array of the indices at which a given character appears in a string?

Maybe I misunderstood perlvar and it doesn't work with /g in list context but only with repeated match groups in a non-global match.

Anyway you should take @- for start, your results show the ends.

Can't test ATM...sorry.

update
Without being able to test, please try

print $-[0] while /n/g

update

now tested:

  DB<100> $_ = " x " x 3
 => " x  x  x "

  DB<101> print $-[0] while /x/g
147

    my $input  = 'rnbqkbnr';

my @results;
push @results, $-[0] while $input =~ /(n)/g;

print "@results";

      Imho that's why hdb got (2,2)

      The first was the end for $& and the second for $1 and so on.
