in reply to Randomise a string of letters

Using the "Randomizing an Array" example from the Perl Cookbook, I threw together the following code. Does this help?
#!/usr/bin/perl -w use strict; my $gStr='This is my string'; my @gStrArr=split('',$gStr); sub fisher_yates_shuffle { my $array = shift; my $i; for ($i = @$array; --$i;) { my $j = int rand ($i+1); next if $i == $j; @$array[$i,$j] = @$array[$j,$i]; } } fisher_yates_shuffle(\@gStrArr); $gStr=join('',@gStrArr); print $gStr,"\n";

[Corion]: Hi Lady_Aleena!
[Lady_Aleena]: Corion, how are things?
[Corion]: Lady_Aleena: Quite good ;) I'm working four days now, instead of five, which helps my mood and my weekends tremendously
[Corion]: My Perl output hasn't recovered, but as $work is still somewhat stressful, I don't think this would be different with a five day workdweek
[Lady_Aleena]: Corion, that is a good thing (TM) 8)
[Corion]: And this evening, I'm actually dusting off some old module of mine and bringing it up to the last version of the library I'm wrapping
