    See

    tr/SEARCHLIST/REPLACEMENTLIST/cds
y/SEARCHLIST/REPLACEMENTLIST/cds

    in perlop. It's around line 1100 in my version.

    Transliteration is what you're trying to do- map one set of characters onto another set. Specifically, you're trying to implement rot6, a transliteration cipher (not much of an encryption, btw).

    tr///, aka y///, uses the second set of characters to replace their counterparts from the first set.

    my $word = "abc";
$abc =~ tr/acb/llo/;
print $word;
