Re: Hash Question

You want to create a module. You'll probably want to read perlmod first. Here's a very basic example to get you started (untested):


############################
# filename: MyFirstModule.pm

package MyFirstModule;

our %common_codes_hash = (
    '000001' => 'ITEM _First',
    '000002' => 'Item B',
    '000003' => 'House',
    # ....);

1;

__END__

########################
# filename: myscript1.pl

use MyFirstModule;

my $whatever = $MyFirstModule::common_codes_hash{$foo};

# ....

__END__
[download]

Later, you can get fancy by using Exporter to export your common data structures or functions into the script's namespace, and other things.

Update: changed the my to our (realized the error at the same time as snowcrash).

`> my %common_codes_hash = (....);` [download] In the module, the file MyFirstModule.pm, %common_codes_hash should be declared with our instead of my. Otherwise it won't work if you put the module and script in two seperate files. snowcrash	[reply] [d/l]

it´s a matter of taste, but i whouldn´t store data in modules but in datafiles, textfiles, databases etc. modules are for sharing code, not data.	[reply]

Except when modules are for sharing data (HTTP::Status, Unicode::CharName , etc)	[reply]
