in reply to regex issue

Please better define what you mean with "three letter-doubles". The two monks that responded previously understood something different, and I understood yet a third possibility.

Please explain and/or provide an example.

    I meant all 3letter words that occur more than once.

      In that case:

      use strict; use warnings; my $term = 'Dit is het eerste het is niet het laatste Dit'; my @tlw = $term =~ /\b(\w{3})\b/g; # Now you have all the three-letter words, so count them my %seen = (); $seen{$_}++ for @tlw; for my $k (keys %seen) { print "$k occurs $seen{$k} times\n" if $seen{$k} > 1; }
