Re: Manipulating key/value output

Merge or replace?

A simple example:

use warnings;
use strict;
use Data::Dumper;

my %hash = (
    output1 => 'on',
    output2 => 'on',
    output3 => 'on',
    announcement => 'test',
);

$hash{$_} = $hash{announcement} for keys %hash;
delete $hash{announcement};

print Dumper(\%hash);

Thanks for the Reply. Not quite what I was looking for though. Basically I want to take the output1 entry and merge it with test while stripping out the = on and anouncement =(if that makes sense) Also not sure if this applies or not, but my variables can change. Sometimes I will have output1, sometimes output2 and output3, sometimes outpout 1 and output4 (can go up to 40 at least). It will vary. The only constant will be announcement = 'whatever the announcement is' The thing that I am wondering now is if I should have output = set as a constant instead of output1, output2, etc.. Meaning env = <this will change> and announcement = <this will change> and then manipulating from there... That might work better maybee??	[reply]
