in thread Array of Hashes in subroutines.

Hi Jean,

Try out the following. It should work
#! /usr/bin/perl use strict; use warnings; sub display { my $ref = shift; foreach my $key (sort keys %{$ref}) { print "$key = ["; foreach my $key1 (@{$ref->{$key}}) { print "$key1,"; } print "]\n"; } } my %hash1; $hash1{'frog'} = ['jumps','swims','slimy']; $hash1{'dog'} = ['barks','swims','hairy']; display(\%hash1);

As someone had mentioned the module "Data Dumper" is really helpful. Even i am still learning and its really fun playing around with these references and derefences until you figure out what is happening. :)
Hope it helped

[Lady_Aleena]: [pad://]
[james28909]: my scratchpad
[james28909]: and like i say, is just an example, not working code, but hopefully you understand what i mean. :)
[james28909]: and like i say, it would be alot of work to get around renaming 3 subs haha
[Lady_Aleena]: Well, you would have to add the file munging and a lot more.
