At the office I have been asked to become familiar with some of the Perl scripts on our Linux system with the eventual goal being I will make some modifications to the scripts.

I have written some small test scripts that load data into judy arrays using both the object and non-object interfaces to the judy module. My test scripts have also done some basic querying which seems to work as expected. However I am puzzled by some of the parameters to the "search()' routine. While looking at the code in the module I am studying I have noticed some values for the "min_key" and "max_key" parameters that I do not understand. min_key => '.' max_key => '/' What are the effects of these parameters to search() ? Since the code I am working on is at the office I can't show all the details, but here are a few lines extracted from the module i am studying

use Tie::Judy;

use strict;
no strict 'refs';
no strict 'subs';

sub work1 {
  my ($args,$parm2,$parm3,$parm4,$parm5) = @_;
  my $search;
  $search->{'min_key'} = '/';

## snip ##

  return(work2($search,$parm2,$parm3,$parm4,$parm5));
} # end of work1


sub work2 {
  my ($args,$parm2,$parm3,$parm4,$parm5) = @_;

my @result = $judy->search(%{$args});

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
